My 36" CRT based TV is going to die soon. I am being forced to find a new main/home theater TV. A lot of non HD source will be watched on it. What I have noticed in looking around at different Electronics stores, is that non HD sources look horrible on the Plasma and LCD displays. Am I seeing this correctly? Since CRTs in the larger size are no longer available, what would be the best to get now taking in to account my non HD source needs?
