Tubby,
Search on Denon DVD-1910, DVD-2910, DVD-3910, Momitsu V880 deluxe, Sony DVP-NS975V, Panasonic DVD-S97S, Pioneer DV-59avi, LG LST-3510a, Samsung HD841, and the Zenith DVB-318. If you want a really bad upconverting player, IMHO, then the Toshiba SD-5970.
The big question: Do you need upconversion via component? If so, your choices are: Momitsu V880 Deluxe, or *old build* Zenith DVB-318 (and never, ever apply a firmware update).
