I'm looking to upgrade my '85 Fuji Club frame. I saw a local listing for this frame for $300. It's a "Ventoux" model, lugged steel Italian hand made. Is this a reasonable price to pay for such a frame (or should I try to haggle)? It seems like a pretty good deal, but I am unknowledgable about the original price of these frames.

Also, it is a 48 cm, and I currently ride a 50 cm.. can I ride a bike that much smaller comfortably?

Thanks!
