I doubt anyone here is dropping $300-500 on one of these with the intention of never using it again. People here seem to be strapped for cash, if anything.
People do that in fact very often. Contax G1, G2 was one example in past, many expensive dSLR's - people pay premium price, and when new model is out - sell old one for <25% price. Just wait when lomo gets Petzval version 2 (and they will get it - why not, it will sell like crazy) - people will sell version 1 for peanuts
BTW - I am second in the line :WTB used Petzval nikon mount
