First post here guys.
Thanks for the link wedweb - it's actually $689 right now. I just moved to the USA from abroad and had a Toshiba set which I really liked in the UK, so I wanted another. I saw this set in Best Buy and immediately wanted to buy it.
I have an amp and speakers so won't be using the internal speakers at all, so audio issues are, well, non-issues for me.
This set looks a cracking deal at the price ($722 delivered).
