I just checked Ebay for used 4120's, which I often do in preparation for selling my 4120 in the coming year. One just 'sold' for under 3 grand, and then there was a current auction -- with the exact same description as the first auction, but in a different state -- that was currently at under 2 grand. A third was offered in a 'private auction' (secret bidders, contact the seller before bidding), and the Buy It Now price was under 5 grand.
Sure sounds like there's a wider-spread scam going on. Can anyone out there confirm or deny this?
