I saw one of these frames today, look nice but I really, really have how the bottom tube is shaped near the BB. Anyway, I wouldn't pay more than $100 for it. New price is $1000, vast majority of that is in the parts, and remember you shouldn't be paying any more that 50% in a second hand sale unless there is an honest reason. Just to compare, I got a .243 frame (RRP $900) in bloody good nick for under $200, and that was with the cranks, BB, and would've been headset if it wasn't stuffed.
Hope I gave you something to think about
