mtbmtb01,
The color seperation issue has been experienced on this forum in a few posts, and those who have been affected have had the issue resolved by Samsung replacing the bezel.
The same goes for the "halo" effect. Some of the televisions had a "halo" effect when viewed in very dark rooms. While the reviews are mixed on the fixes we've provided, I would say that most are satisfied. If you look around this forum (search TOC or halo in this forum at the top of the page), you'll see some of the experiences here.
The A750 is a great set, and many people here have also noted that they enjoy it tremendously.
Ultimately, you have to do what you are most comfortable doing. I recommend looking around to see what people say about it.

i had been looking at this set and saw this on amazon:

i have also heard quite a bit on the halo effect.
can you tell me more about these problems and why i should stay with the 750?
