*cough*e-bay*cough*
Think I may have seen this one. Saw a system on e-bay for sale that included the aformentioned player (pretty sure I know exactly which one).
The ad was for the system, a player, a library of KJ songs and a library of DJ selections. Said he had been using it for shows, and you *cough*had to delete the songs if you didn't own the disks*cough*. (They put that in because it's an e-bay rule that if you don't you can't sell it through e-bay.)
Funny part was, saw like 6 of the systems all from the same seller with the same description. Musta been a hell of a show to need 6 systems and all ...
