I'd spend $100 of that on a few widely-accepted but contrasting books on personal finance and investing. A library card will do just as well. Read them carefully. Price is what you pay, value is what you get. A traditional option is to buy index funds over time. Stay within your circle of competence. If you have to ask if something is within your circle of competence, you already know the answer. If you're in a low income tax bracket, making contributions to a Roth IRA can be very wise in the long run.
