These questions are kind of exclusionary.
Most anything with RGBHV outs will probably be progressive (I know of no interlaced RGB display input); the only way I know to get this is aftermarket (like Cinematrix). However, this may become the next "standard" (like progressive component outputs have become)--although I don't know how quickly (after all, there's not many TV's w/RGB in!).
As for interlaced players, I would assume that many are now similar. Once upon a time, Sony was king (like my old 7000 or now 7700); now it seems Panasonic rules. It looks like you're doing out-board processing of the (S-video or component) signal, so the requirements on the actual player are relaxed (like I said, many use the same chip sets in the "standard" interlaced path).
