Have you ever wanted to buy a round lot of Berkshire Hathaway ( BRK.A) but your brokerage account fell slightly short of the required $11.75 million? Even 100 Berkshire Class B ( BRK.B) shares could cost you more than $391,000. Ratings stock model scores the Berkshire Class A shares with a rating of B and the Class B shares with a rating of A-. Any rating of B- or better is equivalent to a buy rating.

But you do not have to tie up that much of your portfolio in a single stock. You don't even have to pay full price to get the Oracle of Omaha, Warren Buffett, working for you.

The best-rated closed-end fund with at least 50% portfolio allocation to equity securities is the Boulder Total Return Fund ( BTF), which we rate A-. This fund currently trades at a discount of 11.7% to its net asset value, with its largest and third-largest holdings being Berkshire Class A and Class B shares, which together total 39% of assets.

Our stock model is also bullish on three of Boulder's other top holdings, Yum! Brands ( YUM), Wal-Mart ( WMT) and Anheuser-Busch ( BUD).

The next four closed-end funds earned ratings of B+. All five of them have performed poorly in absolute terms. However, compared with other funds we rate on a risk-adjusted return basis, they have performed slightly better than their peers.

Cohen & Steers Dividend Majors Fund ( DVM) is the second-best-ranked of this group, targeting real estate companies and stocks with above-average dividend yields. The average dividend yield in its portfolio amounts to 4.89%.

The Cohen fund's portfolio -- led by Macerich ( MAC), Simon Property Group ( SPG) and AvalonBay Communities ( AVB) -- trades at a 12.8% discount to net asset value.

The third-best-rated closed-end fund, Blackrock Dividend Achievers Trust ( BDV), is trading at an even larger discount, of 14.1%. Chevron ( CVX), Bank of America ( BAC) and General Electric ( GE) headline its portfolio, which averages a dividend yield of 4.54%.

At a 17.8% discount to net assets, the fourth-place Lazard Global Total Return and Income Fund ( LGI) is 85% invested in stocks such as IBM ( IBM), Microsoft ( MSFT), Oracle ( ORCL) and Exxon Mobil ( XOM).

Finally, the Boulder Growth & Income Fund ( BIF) also offers a modestly smaller 29.3% exposure to Berkshire Hathaway Class A shares at a similar discount to the above-mentioned Boulder fund of 11.3%. Wal-Mart and Anheuser-Busch are the next two largest holdings.
