Can someone comment on the Panasonic PT-56WX42 vs. the Toshiba 57HDX82? My main considerations are as follows: 1. Good stretch modes - I will be watching a lot of 4:3 material. 2. Detail - 480p upconversion is a minus on the Toshiba. Also the reported ghosting problems have me concerned. 3. Price - ~$2500 max Also considering... Mitsubishi WS-55411 - This would be the perfect set for me because it is made to for built-in installations and does native 480p. The only hesitation here is that the stretch modes are supposedly not very good. Pioneer SD-533HD5 - Meets all of my requirements, but the screen size is on the small size for the money. Sony KP-57WV600 - Seems to meet my requirements, but I can't find much positive feeback on Sony RPTVs. I know I need to look at these in person, but no store has them all side-by-side properly calibrated, with consistent source and lighting, thus your real world input is highly valued!
