Habu,
It depends on what you prefer. I will do my best as to not confuse you. I will assign brands with types. HT is a hobby of mine
CRT- Loewe Aconda (the best picture of ANY tv, no equal), Panasonic (slightly better than Sony in terms of picture quality), Sony (alot of exaggerated "red hues").
Rear-Proj - Pioneer Elite (the best again), Mitsubishi, Pioneer (BB Pioneer). Everything else. Keep in mind that outside of the Pioneer Elite, that steeper the viewing angle, the picture will get blacker. It does happen with the Elite's, just not as quickly as the others.
Plasma - Pioneer Elite (alot of mullah, but a badazz picture), Zenith, LG. DO NOT FALL PRAY To Gateway and Dell. Yes they are affordable but they ARE NOT HDTV's, they are EDTV's.
DLP - Samsung (the best). I would trust no other brand with this technology YET. While a great picture can be had with them, they have their issue right now. A "rainbow" can be seen on some screens, however, Samsung is really up on how to improve this technology, and they will.
What I think you should look at is the Pioneer Elite Rear Proj. You can literally put your weight on the screen and it not will NOT BUDGE. The 50" should be around $4000-$5000. But you will not find a better picture. The Mitsubishi's are a close second, but the build quality belongs to Pioneer Elite.
I have a 27" JVC that is about 5 years old. I bought the Sound&Vision Tune up disc, and the picture is amazing for just a standard, analog TV. I am looking at the Loewe Aconda 30" ($3000) or 38" ($4500. I have yet, to find a more crystal clear picture. The Pioneer Elite Plasmas are a distant 2nd.
I hope this helps you in any way bro.
