I'm with Greg and others--ofen buy guns that need to be fixed. Three reasons at least--I'm cheap and so are they; I love the hunt for parts and services needed to bring them back to whatever they were before the neglect, and I just love putting one more gun back into service.
(My wife would call this spending $2500 on a $750 gun. That of course doesn't count the time--she knows what my time is worth--and the gas and phone calls.....).
Done this since I was eight years old--that's 58 years of rust, poking into odd corners of old gunshops, and returning the wrong parts to various parts merchants. And meeting some very fine folks in the process.
