Interesting thread. I have the Sony KV-40XBR800. When I bought it in 2002 or so, it was certainly the best 4:3 TV I could find that also supported HD up to 1080i. I remember seeing NFL Sunday Ticket in HD, wow. There were a few monster Pro-Scan 16:9 CRTs at the time as well, but lack of HD content pushed me to 4:3, where 95% of the channels would be broadcast.
I am gonna sell it though due to lack of space. It is certainly large, and takes 4 people to move. The HD picture still looks far better than any LCD. Similar to a Plasma. I played Intellivision, Dreamcast, N64, SNES, and XBOX through it. The only Dreamcast annoyance is that the Light Gun does not work on Progressive Scan screens.
PM me if interested, its in Central NJ. Includes the matching Sony stand with glass shelves as well. Trying to avoid Craigslist BS....
