I picked up the 85 at Best Buy. I was going to get the 75 but my wife wanted the changer and it was only $24 more, plus I prefer black.
I'm not a videophile, but the PQ seemed great to me. I'm using HDMI connection, set to 720p. I have the player set to "Cinema 1" mode, and I left the 2 noise reduction options on. I just did a quick calibration of my TV using the THX Optimizer on Star Wars Attack of the Clones. I browsed some scenes of the Star Wars movie, The Incredibles, The Red Violin, Star Trek Insurrection, and The House of Flying Daggers. All looked a bit crisper and more detailed to me than my previous old component/480p DVD player.
PQ is not quite up to OTA HD (Lost, The Unit), but very enjoyable nonetheless.
While I find this DVD player to be an improvement thus far, I only bought it because my old player died. Otherwise I probably still would be satisfied with the lesser PQ of my old player.
For those curious about TV settings, my TV is a Samsung 40" LCD, LNR-408d. Going from memory, I think I have my settings at around 85 contrast, 34 brightness, color at 40, Warm 2, Sharpness at 50. I will probably end up lowering contrast and sharpness a tad at some point.
