I have a brand new never used Yamaha RP-U200 available for purchase. I bought it over a year ago but never ended up using it because I got lazy and bought a stereo system for my TV. The only thing missing from the box is the UPC label which I cut out for a rebate submission. The original MSRP for this was $449.
