I just bought a 46" Toshiba Regza 1080-LCD-HDTV Clear Scan...and it's great! Got it at COSTCO for like $800...which was priced like half of the Samsungs and Sonys. I am usually a Sony guy, but they were side-by-side...and I could not tell any difference in picture quality, especially on blue ray. I chose price over name...as by the time this one needs replacing, technology will be that much further along. Besides prices continue to go down as new technology is discovered. Look at plasmas... When they first came out, they were like $15,000 for what you can get now for $900...
The Toshiba was such a good deal, I bought another 19-inch flatscreen Vizio for the kitchen for $160 and a wall mount for $80....all at Costco..
