Make absolutely sure the headset parts are complete. It is a proprietary Bianchi integrated headset and it will be hell to find another one.

Read this thread - about the (possible) bottom bracket issue. http://www.bikeforums.net/classic-vi...und-rough.html

Also budget $100 for the special VAR pin wrench (or two) necessary to work on the headset. Unless you have a LBS with such tools, or can improvise an alternative.

I think there is quite a good chance the frame will not sell at that price. In that case, you might be able to negotiate a lower price w/ the seller, or see if he has the appropriate BB should this be a frame requiring the wider BB.
