I want to get a full suspension bike, but im on a budget. My friend got one at Wal-mart for under $100. Now I know what you all will probably say about the whole Wal-mart bike thing, but what are my alternatives. Also, if I could put it together myself, i'd like to. Any help finding a bike would be so appreciated. Any sites that sell used, or good but low priced bikes would be good. Around $200 is what im looking for.
