I just bought a Toshiba 27A34.....for some reason one Target store had it on clearance (I still don't understand that one) and I got it for $160. Everywhere else, I've seen them for $229, which still isn't a bad price.
Anyway, most say that you should use component (not composite) connectors for doing video, because they're supposedly better than s-video. But not everyone agrees.
I'm personally looking at using the XP Pro from GrandTec (
www.grandtec.com) to run a VGA port to my TV. Then I should be able to use S-video or component.
Other people say that you should get an ATI Radeon card with DVI out and then use a DVI/component dongle/cable to connect it to the TV. Then you've gotta use Powerstrip software to get everything to work correctly. I like the XP Pro idea better because then it should work from any VGA port, and thus it should be easier to transfer between computers.
As far as using TVs in general, I've heard that sometimes text is hard to read, but I've also heard the opposite.
As for the bezel. I'm thinking about just using smoked plexiglass. Some say that it it's good enough, because all you see is what's lit up on the screen.
For overheating, I wouldn't think it'd be a problem as long as you have proper ventilation. I'm planning on installing a fan or two in the back/top.
FYI, you should check out some of the FAQ threads, and do a search. There are several lengthy discussions on s-video vs composite, etc.
