Farmerboy08, you're not doing this right. Select something that's not overly-ambitious, find lots of videos of it on YouTube, show them to your parents and I bet you'll get them to buy the parts. Put it this way: The $50 bot only costs about $50 and you get to learn a lot of stuff, and it's safe (you're only working with small-powered batteries, they can't hurt you unless you swallow them and I'm sure you're over 3 years old so you're safe). I'm an parent myself and I'd support my kid in doing something like this, especially if he put this much effort into it. On the other hand there would be some kind of punishment if he killed his psp to get 2 cents worth of parts.
