They have good reviews by most accounts, the biggest problem in the past has been humming from their power supplies, whether or not this is still the case I have no idea.
I believe Cam had an issue with his 58" Plasma and the panel was replaced(?) or I might be thinking of my inlaws which had a similar problem and I know the panel was replaced on theirs. As I mentioned in another thread, if you like the PQ, size and the price, buy it. researching them only makes you frustrated as there are problems with all flatscreens that people can find fault with, just look at AVS forums on flatscreens, on second thought don't it drove me nuts reading all the positive comments only to find almost as many negative ones.
