I'm looking at both of these sets and I wanted some input from the pros. The only major difference that I can see is the 82 is DVI upgradeable. I am concerned about compatability when the HD spec is finally decided on, however, I also think that when it is decided there will be kits available to adapt sets to the new spec. Please post any and all thoughts because I'd only like to make this purchase once. (that is until I can safely rationalize an upgrade) Cheers. J.
