[quote name='mobster011']high contrast? is that an option that you can customize by turning it down?[/QUOTE]
Yes, keep it below 50% when watching normally.
Turn it down to about 1/3 when playing games (or anything with lots of bright static images). You should be fine. As long as you don't put the contrast too high your Rear Projection CRT TV will last along time.
If the thought of burn in scares the crap out of you, just remember it is faint transparent like image. It is really just the area on the CRT(s) that is wearing faster then the rest. It is not burned on the screen. There is nothing you can do about the wear. At any moment when your TV is on the CRT is wearing. With higher contrast it just wears faster. See
CRT Tube Condition
If that still scares you look at a digital display: DLP, LCD, Plasma. If you get rear projection LCD or DLP you'll have to consider bulb prices ($200+ each) and how long they will last you.
Plasma has no bulbs and the newer panels are nealy resistant to burn in, but they do cost more in some cases (check out Wal-Mart, Costco, and Sam's for rebadged Panasonic or LG Plasmas on the cheap - Maxent, Vizio, there are others).
Also, because of Costco's and Sam's liberal return policy, you should not need an extended warranty on a Plasma or CRT if you buy it there.
