I built my bike recently too. Yeah, my wife espically thinks I'm crazy. I spent about $500 total (not counting costs of parts from old bike) on a Santa Cruz Bullit
Got the frame from one guy, a Marzocchi Z1 MCR fork from another guy, new chain, and just threw the rest of my old parts on it. It's a great bike, and fits me well- something you can't really get from an off the shelf bike, you know?
