Re: wanting vs. needing--big screen tv
We have a 65" WD-65831 (Mitsubishi Diamond DLP) in the living room and absolutely love it. Also have a 50" Vizio Plasma in our office which is pretty sweet (gives off a ton of heat though) and a 37" Westinghouse LCD in the bedroom.
I mention these because each has their own drawbacks...
-DLP has a lamp inside that can be fickle and is the largest of the bunch. But an incredible picture. Thin viewing angle, if that matters to you.
-Plasmas can get really hot and give off quite a bit of heat and use a bunch of power
-LCD doesn't have as good a picture as the DLP/Plasma, but more than acceptable.
I would HIGHLY recommend getting one as you really don't know what you're missing until you watch a movie or game on them. Just fantastic.
But, my biggest suggestion is to wait until you can pay cash (just in case) as well as taking a trip over to avsforum.com. That is THE place for all electronic discussion and those people really know their stuff.
Compare, ask questions, find one and get it!
Good luck and enjoy!
