IMHO, with 4:3 content still being the most widely used for OTA/Cable/Satellite signals (as well as some dvds), if you are on the fence about 16:9 tv's, a 4:3 set that does a proper "raster squeeze" is a good choice.
I purchased a 36XBR400 set for precisely this reason....good sized/quality 4:3 set for my family's 70% cable viewing, with a good widescreen mode for watching dvds and HDTV.
Cheers,
