I wouldn't pay more than $600 for a MINT steel 9 speed Zurich. No more than $250 for a MINT frame and fork.
Personally I don't buy high end steel with dents or rust...it kinda defeats the purpose of having a nice steel frame.
To me that 9 speed and wheelset are junk. I'd strip it, sell that crap, and put a ten speed group on it.
Check for rust EVERYWHERE...check for little bubbles under the paint, get a flashlight and check inside the tubes. Little places too like bottom braket, head, etc.....where ever water can get in.
A nice light steel frame only rides nice if it's like new. Once you start grinding off rust, welding cracks, and repainting it loses a lot of its quality and rides like a shitty chro-mo Surly, SOMA, Fuji, fixie, etc....they're all the same really.
