“PN58B650 plasma TV - good size, great color and black blacks”
I originally purchased an LG 60PS60 plasma TV. It suffered the common problem of the Y buffer board going bad. This item was backordered for at least several weeks and rather than wait longer I asked and Sears graciously agreed to do an exchange. I really wanted the larger Samsung PN63B550 but at $3,300 it was way over my $2,000 budget. I decided on the PN58B650 which was slightly cheaper than the LG. I've been extremely happy with this unit. Compared to the LG, the colors are richer and more accurate (to my eye anyway) and the blacks are darker. Another big difference is the Samsung has superior anti-glare, anti-reflection. I have the TV in a large den/kitchen room and there is a lot of sunlight that comes in. I no longer have to change my viewing position to mitigate the glare/reflection. I haven't followed any regimen to avoid image retention (IR). I just selected the pixel shift mode and pretty watch whatever and haven't seen any IR. Lastly, some forums report commons problems such as pink hue and buzzing. The unit I have has excellent color with no anomalies and it's absolutely silent. Maybe I got lucky.
Sears sales and customer service were both excellent and they are my first source for buying large ticket items when they go on sale.
