Personally, I would not pay more than $500 for a stem wound 240 alarm movement, and probably not even that. I'd buy at $300-$400, depends how much you need/want it, I guess (got mine years ago). And a working key wound I'd buy at $100-ish, for parts (or to replace a SW in a weather station and keep the foursome/sixsome working).
