i have a sony bravia 40 inch, and a toshiba regaza in 32''. im happy with both. i'm thinking of upgrading around christmas, but havent really shopped around.
if you're going with a player of some sort all i could say right now is go with the PS3 for blu ray. apparently some of the stand alone blu ray players have load times of over a minute. the ps3 loads quickly, updates online, it's wi-fi capable and functions as a dvd player as well.
if you're thinking of an xbox 360 i would hold off. the xbox with all its features and with xbox live (you can download movies in 720p) doesn't have a viable hi-def option anymore. they have a portable HD-DVD drive but with toshiba dropping out of the high definition movie market they are more or less obselete (think beta-max back in the 80's) there are whispers of microsoft releasing a new version of the xbox 360 with a built in blu ray player but i don't think that's been made official yet.
oh and one more thing. as for your cables. don't get sucked in to buying "top-end" brand cables. brands like monster cables, or next-tech, are just brand names. you can get generic hdmi cables, or component cables from places like ncix.com (broadway and burrard in vancouver) for literally 10% of what future shop or best buy is selling them for. i picked up a 8 foot hdmi cable for 16 bucks at ncix, while future shop wanted minimum $50.00 for their bottom end models.
