Gooddomino:
If you are going to keep your Sony XBR for about another five years or so (which is about the same amount of time I am planning to keep my 27-Inch Panasonic "SuperFlat"), then I wouldn't worry too much about getting a progressive scan player, unless that is what you want from the outset. If you still would like to get a progressive scan player anyway, then I concur with "Jaica" above in reference to the two progressive scan players "Jaica" is talking about. But I would also look at a Toshiba SD-3750. You should be able to get one for around $200.00 or so. I don't care that much for the low-end Pioneer progressive scan player at all. If you should ever opt for a Pioneer progressive scan player, then the only models that are worth looking at are the Elite models. Otherwise, for your set, a good interlaced player should be all that you need.
