This is how I like to invest as well. I use the Magic Formula stock screen - the point of the strategy is to find good companies (high return on capital) at low prices (high earnings yield). Then check out the long term moat characteristics to make sure a stock is not a flash in the pan. You definitely have some excellent companies there, but a stock does not have to be owned by Berkshire to have these characteristics. Look at some of the smaller caps as well, even Buffett has said that these offer the greatest gains for the individual investor.
