My last 3 TVs have been Toshiba. Originally, I bought the first one back in 1997, primarily because it was the least expensive, and I needed a TV. I was happy with the purchase. Quality was satisfactory, and features were more than acceptable. So when it was time for me to upgrade 5 years later, the first TVs I looked at were Toshiba. I looked at other brands, but taking into consideration price, picture quality, and features, Toshiba still came up on top (with JVC coming a close second). And 2 years later I bought another Toshiba, 34", S-video and Component connection.
Of course there were better TVs in the market, even though the picture quality was better, it wasn't THAT much better, that I could justify paying $200 - $300 more.
But those were CRT TVs. With LCD techonology getting better and better, and cheaper and cheaper, there are more brands to chose from. From my own research, I've narrowed my list to LG, Samsung, and Panansonic, when I'm ready to go HD.
