They go for between 3 and 4 hundred on ebay. That said, I know someone here in Iowa that has one, and he is always bitching about it. Apparently after heavy use, one of the sides appears to crap out. I don't have a home dat, and if I were to buy one now...which I will [probably do after I ditch the m1, hopefully in the next 6 months, I would get a sony r500. They can be had used with very little hours from ebay for around 400, which sounds about right to me. One thing about ebay, definately ask the seller questions to make sure they know what they are talking about.
