Samsung LN46A750 46-Inch 1080p DLNA LCD HDTV With RED Touch Of Color

I am still extremely impressed with this television one year into ownership. The picture quality is simply outstanding, and it looks great hanging on the wall.
It has a built-in sub-woofer which helps the sound quite a bit (this is a step up over the 650 model). We almost always listen with just TV speakers, so it was important to me. However, at low volumes, the sound is a bit 'tinny', which is par for the course with thin TVs. Overall, I'd say the sound is top-of-the-line for a flat panel TV, so don't let this deter you. Listening at normal volume, the sound is better than the large CRT we were using before.
Some people complain about a 'halo' around the edge of the screen, and some cosmetic peeling of the 'Touch of Color' (inside the glass of the bezel). These things exist, but they don't bother me. The halo is easily solved if it irritates you (just search around, there are a couple ways to do it), and the peeling is so tiny, I can't believe how much people were commenting on it. You can't even see it unless you're right next to the TV and looking for it. Maybe we just have a mild case of it.
The glossy screen concerned me before I purchased - it almost kept me from pulling the trigger. I don't regret it in the least. Now, when I'm looking at TVs for other rooms in the house, I find I WANT a glossy screen because of how attractive it is and how deep the blacks are (note - I don't care for them on laptops because of glare). However, be wary if there are lots of windows in the room that shine on the TV. If you're sensitive to this, it could bother you. (I still think it's worth it, personally.)
I also use the TV for gaming (Playstation 3). I don't bother putting the TV into 'game mode' (which it has), and have zero problems with lag. Maybe I'm not that sensitive, but I've never noticed any lag at all, actually. I keep my AMP (Auto Motion Plus?) setting on 'Low'. Higher settings seem to cause erratic visuals in fast moving scenes, and I suspect will cause some display lag as it does the extra processing.
Purchased from Amazon, which was no hassle at all (I was concerned about buying a big ticket item online). I won't hesitate to buy a TV from them again. We had zero dead pixels, so no returns were necessary.
Finally, note that there is a newer model of this TV (the B750) which is apparently also excellent (I did some quick research). Although I have no first hand experience with it, it's possible the B750 has a bit more lag than the A750 (if you're looking to use it for any kind of gaming). Honestly, I sincerely doubt that's an issue and I wouldn't hesitate to buy it.
I'm thrilled with my purchase after a year, and would buy again in a heartbeat if the need arose. We have had zero problems with the TV in that time, which speaks for its reliability.
