Thanks for the info AJD, that's awesome. I know basically nothing about HDTV's, so that's really helpful.
When I went to FS the main thing I did was really just look at the TV's and see which one looked best. I'm mostly just wanting a TV to play my games on - so I figured 1080p would just whoop 780p. It was really just hard to tell any difference, because whatever channel was on the TV's just looked like complete ass at FS - but it looked nicer on the Insignia, so that's why I was liking that one more. Thanks for the info on the warranty as well... because if I add the 2 year warranty it's an extra $130 on top of that, and I can just imagine what else I could buy with the money I'd save not getting the warranty.
I'm still going to have to keep looking into this I'm thinking, but thanks for the advice. Hopefully next time I go to FS they'll have the TV's set to a decent channel, because the only TV's that looked decent were the $1500+ sets.

One other question - I believe all TV's have an "environmental fee" or something like that when you buy a TV, and last time I got a TV for $90 and it was $25 for the TV. Does anyone know if this goes up if it's a more expensive TV, or is it $25 for any TV?
