My two working Kowa SIX bodies, and about five lenses (two sets of the 85 and 150, plus a 250), with two grips, cords, a bunch of filters, and a really sturdy box ran me $200.
I'm not usually one who runs across great deals, but this was one of 'em. The seller tells me that one of the bodies has a minor light leak, which only seems to happen in bright sunlight, but that he just kept a roll of electrical tape handy and kept on truckin'. They seem pretty darned stout to me, save for the bail on the back release, and the crank lever, which I don't use anyway.

I like the setup, but I am aware of the age issues... more about the lack of repair shops nearby... Sure I'd swap it for something that circumvents that issue, but they are kinda fun anyway.
