Stainer711,
You could always try going into BB or CC and tell them you are looking into buying a HDTV, but you need to see if how well it will display on a laptop, you know because you want to buy both, but your not sure how well it work together. They should be able to take it over to one of the CRT's and use the s-video display to show you.
I'll see if I can get one to do it today or tomorrow since I'm looking into a new computer.
Also good point out Anthrax of Analog v Digital, Though I'm thinking HDCRT would have to be digital sinve analog degrades so much over distance.
