I'm in the market for an HDTV and would like some input on a few differences I've been reading about. LCD versus LED. I've read some reviews about the SONY XBR series 240Hz HDTV's and some white streaking on black back-ground on the screen, not much as far as Samsung comparison with the Sony except for the price. Then I read some reviews for the Samsung LED HDTV's at 120Hz 1080p format and I've read nothing but pretty good reviews. Any comments on which way to go before I spend the cash they're asking for these HDTV's? Any comments/advice welcome!
