Sharebuilder

The idea is simple.  Let's say you want to invest in an individual stock, but you can only afford $20 a month or so.  Well Sharebuilder will let you do this.  The only thing that catches me off guard is that it cost $4 per automatic investment.  That would be 20% fee on a $20 investment.  They do offer some no transaction fee mutual funds that you can invest in, and those have no charge so obviously that's the way to go.
