I have one and PQ is identical to RP62 (DCDi also). I don't own the RP82 or XP30. It is not as well built and has the subtitle bug (it pops on without cause for a few seconds on some movies (20% of time). I got mine for $99 at hhgregg's (CC type store locally in Louisville, KY and Clarksville, IN). You can also buy the new Mitsubishi that has DCDi builtin (6040-8040 models) for under $200. Not sure how the MPEG decoder is but deinterlacing is DCDi.
