Just to add: 99% of people won't see any difference between the $60 Monster HDMI cord and a $10 HDMI cord off Amazon. Yes HDMI cord is a must (a waste to not use one!), but one doesn't have to shell out $60 for a decent cord.
Pretty much everything you read will confirm this, and for anecdotal evidence I compared a cheap $10 HDMI cord and a $125 Monster cord from a buddy of mine who swears by them. There was noticeable difference between the two when I used them to hook up my Xbox.

On a side note, glad you're enjoying yours! I was going to use Blu-ray as an excuse to get a PS3, but they're dropping in price so fast probably can't justify it. Will probably wait to get one this X-mas on super sale (maybe a new TV, too! Mine is old(er) and only does 720p).
