It adds up so quickly. I got a killer eBay deal on a Gunnar Street Dog frame, which I originally set up with a lot of parts I already had. Now its went from having a carbon fork to a Kelly steel fork. Chris King headset went in. Fizik saddle went on, then came back off in favor of an old Brooks I found. Bought new weels. New bars. The frame is currently at the powder coater. I'm sure its over a grand now. Luckily all the parts you go through on these projects trickle down to other stuff. I used most of the extra parts to put together a Surly Pacer, that rides excellent. Bikes are a bottomless pit of money, but still way cheaper than cars.
