It's always interesting how fast sellers raise prices, even on the stock they already have. I suppose it's true what one guy said - Leitz wouldn't sell any MORE cameras if they were $2000, or any FEWER if they were $4000. Given that Leicas are, after all, something of a 'niche' market, the French outfit that reportedly owns a glob of Leitz stock wanted to make them even more esoteric.
My one and only Leica is an M4-2 that I bought new when it was the current model. Of course, that's back a few years, but it's still a fine camera, and should stay that way with the moderate use it gets.
