Price really depends on where you buy them from. I bought my M3 about 20 years ago from Leica dealers, body at one, Summicron at another, meter at a third. But for that I knew the camera body had been serviced and fully tested.
Now I guess I'd buy from ebay, or the classifieds here on APUG, can't help with prices, but there have been some excellently priced Leica's sold here recently.
I've been buying back into Leica in the last year or so - best price I got was an M2 in Exc++ condition for £220 with a seized shutter release, perfect after a CLA for £110. Cheapest Leica I ever sold was a wartime IIIc, awful chrome, half of it hanging off, mechanicals worn out (poor materials), which I sold for £100 as a shelf ornament.
