I had a Samsung TXM3096WHF, purchased @ BestBuy B&M for $900 w/$100 GiftCard MIR.
First off, the TV is not 200lbs. The 27" is 101lbs., the 30" is 122lbs. and the 32" is 148lbs.
My sample was extremely sensitive to magnetic interference and black level was very poor (did the AVIA calibration and dropped the gamma in service menu). When adjusted to produce a satisfying black level, all the shadow detail was lost.
The right side was severely pincushioned.
It doesn't have independent color/contrast settings for each input.
I imagine most of these problems could be addressed with a professional calibration ($250-$450), but that would severely reduce the "Bang for the Buck". If you get one that works well, then enjoy HDTV. I wasn't so lucky.
The warranty is 90 DAYS LABOR/1 year parts/2years CRT, per Samsung's warranty card (in the box). BestBuy states that the warranty is 1yr. labor/1yr. parts. As far as getting reliable information on the coverage of their extended warranties, I would NOT take the word of any employee of BestBuy. When push comes to shove, documentation may be your only support.
Oh, and a 32" 4:3 will have a widescreen image that is comparable to a 30" 16:9, the 32" being slightly smaller.
