Can't say I've seen any on ebay that sold for less than $200 (K1). My other debate is, no matter what I buy, I'll probably want to upgrade to the K3 (or whatever it ends up being called) whenever it comes out. I'd be kind of annoyed if I bought a K2 now and in 6 months there was a new model :-)
I think I've convinced myself to buy a refurb K1. Thanks for all your responses!
