Don't have a set budget, since I know I'll be spreading things out over at least a few months. That being said, I'm not looking to build a top of the line bike, or a piece of crap. I guess if I could keep the entire bike at or under $1,000 I'd be happy. When I originally thought I was going to buy a complete bike I had budgeted about $500. I hear building usually costs twice as much, so I'm prepared for $1,000.
