RE: the LCD discussion
LCD and plasma TVs, along with some projection TVs, can have a pretty big lag problem. I'm not personally sure of the amount of lag (# of frames), but it's noticeable in tournament play and it seems to vary slightly between TVs. While they can sometimes be adjusted with hookups to lessen lag, in my tourney experience, not all flat TVs can feel likea CRT. and that'll really screw up a tournament match.
Some rhythm games (guitar hero, etc) even have a built-in lag correcting "calibration" setting to fix this.
CRT or old-style "box" TVs generally don't lag, so they're the preferred tournament setup. I also have a good rear projection TV that doesn't lag so that's nice.
If I can carry it, I'm planning to bring a 32" CRT with a gamecube to this tournament, so that'll add a whole setup for play
