Hey Lisa,
I agree with you about load mutual funds. However, the American Funds are good funds when it comes to the investment choices they make and have a good long-term track record.
I do not personally like Vanguard funds despite the low fees. Most of their funds are basically index funds which simply mimic the performance of the stock market, which hasn't been a good idea for over a decade.
If you are going to invest that way, you should simply buy exchange traded funds (ETFs). They are just like mutual funds except with much lower fees and they trade like stocks on the stock exchange. You can buy them through any brokerage firm, even the firms that allow dollar cost averaging techniques like Sharebuilder.com and Folioinvesting.com.
