Update - Best Buy was not able to deliver the 720P TV on a schedule that worked for me, so I nixed that deal. I was then able to find an excellent deal on a 1080P S30 Panny. Got the TV set up last night - very pleased - everything looks good on this TV (even non-HD content). Mfg date is Nov, 2011, which helps mitigate my concerns of power supply problems.
Happy New Year!
