I also love my capo. I bought it as a complete bike for $800 from my LBS in flat black. It was my second fixed gear and while some of the components on it aren't top of the line, they're not complete garbage and I'm sure they'll do just fine for a while. Over time I sold off most of the stock parts and now the only thing left stock on the bike is the headset (but I went a little overboard). As long as that frame and everything are in the condition that he says it is, I wouldn't feel duped paying $600-625 for it. Just make sure the frame is in mint condition. Also, he says he's including some Nitto Bullhorns. I could be wrong on this but I don't think Nitto makes bullhorns in a 31.8 clamp size. You could use a shim, but I wouldn't recommend it. Anways, I say do it. It's a great bike and I love mine! Good luck.
