what about that lucky chinatown shop? i read on a thread he carries many rolleis.
if you're going to buy on ebay.. do beware that you're likely to get the short end of the stick. i bought a couple of cameras (of lesser value).. items are not always in the condition described, and you'll probably still have to get them fixed/tuned up at a tune that exceeds buying a functioning unit here/elsewhere.
i would say to post an ad at rangefinderforums.. but it looks like the site's been down for a few days.
