I got a phenomenal deal from a friend/fellow Ape Hugger, with $1000 for a VG M6 (not TTL) body only. From what I've seen you'd be looking at more than that, up to about $1500.
It's a great camera, and I picked mine up with the idea of it being something I'd own and use for decades. "If I could only have one...", sort of idea.
A side idea: you might want to look for an M4, M4-P/2, as the body is very similar to an M6 -- only minus the built-in exposure meter. I either eyeball my exposure or else use a small handheld meter....something to consider.
