I'm seriously considering getting a DVDO Edge scaler. It has the same chip as as in the BDP-83, but with all the features enabled. My Pioneer DVD player can output 480i over HDMI (most players are limited to 480p, thus already applying deinterlacing less than perfectly), so that'll be an ideal base for scaling.
My display can only do dot-by-dot pixel perfect with no overscan at 1080i/p. Some games, bonus content on BDs, and the Netflix streaming disc for the PS3 get output at less than 1080, so having something which can scale any video source would be great. Plus it'll give me more than the 3 HDMI inputs which my receiver is limited to.
