I can see people asking $750 - $1200 for the 222K machines, but not for a 221. At a glance, they can be mistaken for each other... is there a chance that some of the ones people are seeing for the really high prices are 222s?
That said - in Canada - the 222Ks seem to be coming down as well. I know of several that have sold for under $300 including the one I bought about 2 years ago now.
