"Canada's tar sands are in fact the largest proven oil reserves outside of Saudi Arabia. Tar sands are already 65 percent of overall Alberta oil output and are expected to hit 88 percent by the end of the decade," says Roger Conrad.

The editor of the specialty newsletter, Canadian Edge, reviews a trio of oil sands producers -- Penn West Energy Trust (PWE), Suncor (SU) and Cenovus Energy (CVE) -- that he states "truly worth investing in."

The advisor continues, "Starting with the most conservative, Penn West Energy has inked a joint venture with giant sovereign wealth fund China Investment Corp (CIC) to deploy the latter's capital to develop its oil sands properties.

"Our high-income stocks are doing well; but lately, I've wanted to add a high-income play in the oil and gas sector," says Mark Skousen.

The editor of The High Income Alert explains, "So today, we're returning to a Canadian energy trust by purchasing an issue that we've traded profitably before: Penn West Energy Trust (PWE), an actively managed trust with a large and diversified asset portfolio, experienced technical teams and a strong balance sheet.

For 25 years, Steven Halpern, editor of TheStockAdvisors.com, has surveyed the leading financial newsletter advisors asking for their favorite stocks for the coming year. This article is one of 100+ ideas in the Best Stocks for 2008 report.

"A top speculative idea for 2008 is Calgary-based Penn West Energy Trust (NYSE: PWE)," says Jack Adamo, editor of Insiders Plus. "We would consider this stock a 'smart money' buy.

"Commodities guru Jim Rogers said four years ago that energy prices would go a lot higher and stay there longer than anyone supposed. We believed him, and loaded up on energy, with spectacular results. We're up 45% this year alone.

"The thesis still stands. Within five years Mexico, our second largest oil supplier, will be a net importer of oil. Prices will remain high.

"Penn West Energy Trust is out of favor because Canadian tax laws change in 2009, and it faces corporate taxes. But with the units currently yielding 15%, even a few quarters of lower payouts in a recession, and a 30% tax bite in 2009, the units will still yield near 10%.

"With its long-lived reserves, the company has good growth prospects to boot. Great for current income or long-term total return. Buy up to $33.50."

Two of the savviest advisors around are Mark Skousen and Richard Lehmann. Both are noted experts in income investing and both have recently issued buy recommendations for the same stock.

Skousen, in his High-Income Alert, and Lehmann, in his Forbes/Lehmann Income Securities Investor, both look at Penn West Energy Energy Trust (NYSE: PWE).

Skousen explains, "The dollar continues to slide. Oil is approaching $100 a barrel, and gold, a sign of global instability, now is above $800. And the mortgage credit market continues to soften.

"All of these conditions make it difficult to profit, even in our high dividend-paying stocks. Fortunately, history is on our side. Studies show that a well-diversified portfolio of dividend-paying stocks tend to be more stable during difficult times.

"Our safest position is in oil stocks, so we are going to add another oil & gas stock to our portfolio: Penn West Energy. The trust bought out Canetic recently to create the largest oil and gas trust in North America.

"The combined trust is worth more than $15 billion and has the equivalent production of more than 200,000 barrels of oil a day. Penn West holds interests in western Canadian oil and natural gas pools, along with opportunities in oil sands, coal-bed methane, shale gas, and enhanced oil recovery.

"Penn West is paying an incredible dividend that now is about 35 cents a month, compared to 30 cents a year ago. The company's current dividend yield exceeds 13%."

"Since tax changes on Canadian trusts were announced last October, their valuation premiums have vanished," notes Gavin Graham, contributing editor to Gordon Pape's The Income Investor.

And while the advisor notes that takeover speculation alone is not a reason to buy oil and gas trusts, he says, "It would not be unreasonable to wonder if a number of foreign oil companies aren't running their numbers on some of the large Canadian trusts."

One favorite, which he calls a "blue-ribbon energy trust" is Penn West Energy Trust (NYSE: PWE) -- one of the largest oil and gas trusts listed on the Toronto and New York stock exchanges. The firm is involved in gas, light crude, heavy crude, and oil sands operations in north-eastern British Columbia, Alberta, and south-western Saskatchewan.

He notes, "Penn West converted from a corporate structure 18 months ago and therefore has a long track record of proven delivery. It is run by Murray Edwards, one of the most successful Calgary-based oil entrepreneurs. Overall, we believe Penn West offers a good combination of current income and growth potential."

Penn West Energy Trust (NYSE: PWE) is a top conservative idea for 2007 from income expert Richard Lehmann, editor of The Forbes/Lehmann Income Securities Investor. He explains, "I am a steadfast believer in the Canadian oil and gas trusts, despite the Canadian government's decision, on October 31, 2006, to begin taxing the trusts as regular corporations after 2010.

"Currently, the trusts pay out income to investors as dividends and are not taxed on the corporate level. In addition, these dividends are treated as qualified dividend income for U.S. investors and subject to the preferential 15% tax rate.

"Recent proposed changes in the Canadian tax law slammed all trusts and brought PWE down from $37 to a current price of $31. This brings the yield up to almost 12%. I like Penn West because it is one of the largest trusts, with over nine years of proven reserves and extensive holdings of unproven ones.

"They have four years to restructure their finances to offset the increase in taxes -- something that may not even come about if past lobbying efforts are any indication.

"Given that the current dividend represents only 63% of cash flow, the monthly dividend is safe from cuts down to a $50 a barrel price for oil. Investors are likely to sell shares of Penn West to lock-in tax losses in December, but I see price appreciation early in 2007 as investors buy in for the irresistible yield."
