$750 Canadian/$500 USD is a lot of money for a good TV nowadays.
I'm a big fan of the Toshiba "PURE" flat tubes. The best price I can find online for their 27AF42 model is $428 USD. The next bump up, 32", I found for $626 USD, if you wanna go crazy on spending.
LinkieFlat 27", S-Video input, 3 A/V inputs, component input, AV output. The colors are sharp and the input quality is phenominal, even on the A/Vs. It's not digital or high def, but if that's not a concern, the PURE flats are great.
I have the 20" model, my Cube is connected using component, the DVD player to S-video, and anything else to the AVs. And the remote is a nice, big universal one, if that matters. (too many TVs sell with crappy remotes these days.)
This is a premium line selling for a premium price. They do have a cheaper line of TVs, but they're basic sets, not flat screen, not as good clarity or sharpness, etc.
