I wouldn't buy a 17" LCD. A 15" LCD is the equivalent of a 17" CRT monitor which is plenty of resolution for the whole family. Get one with a low MS like

Krycheck said or it's a waste. You can tell the blur even while using the mouse in Windows if the LCD has a slow enough response (most of them). Games are even worse -- the response time is the biggest aspect to look for when buying one. I plan on getting one when someone gives me an extra $400 for a 15" one with low MS. I'll stick to my 70 dollars a pop 17" CRT now though.
