I used to look at Ibanez RBX100s and 150s when I was younger and the whole Nu-Metal scene was blowing up. They're cheap: around $100-$200.

Squier by Fender is a little bit more pricey depending on what your looking for. $100-$300

But if you want seriously cheap, go with Rogue. I've never played one, so I can't tell you if they're any good or not. I guess it just depends on how well you treat it (just like any other instrument). $99-$200 ($200 fret-less 6 string, wha?)
