Re: Need advice in buying a new TV...
not really a target price point so much as what you want and can afford. As I've said, I think DLP is the best solution for your setup, so read reviews (avsforum.com is an excellent resource) and pick the model you think is the best, and the right size (really 55"-60" sounds right for your setup), and then check out the websites of the electronics companies in the area so you can get an idea of prices. When it goes lower (and agree that December is probably better than Thanksgiving), buy it.
Perhaps, if I am very lucky, the feeble efforts of my lifetime will someday be noticed and maybe, in some small way, they will be acknowledged as the greatest works of genius ever created by man. ~Jack Handey
