Sharebuilder is a great way to invest without spending a lot of money. You pay only $4 per investment and you can invest a set dollar amount rather than having to buy whole shares. Every Tuesday they pool everybody's investment together and invest all at once. So, you get to own stock in whatever company you want.
I own .9 shares of Starbucks that I paid $10 for and have already made a dollar. I bought .34 shares of Amazon for $21 and its gone up $4. It's fun and low risk.
