The one thing I never do in SW-ville is worry what George Lucas thinks of us. When I bought the OOT DVD last September, I didn't think, "George is laughing all the way to the bank on this one!" I bought it cause I only had crappy bootlegs that always froze up, and atleast these were a slight better quality, and I knew I could watch my favorite movies straight through for 2 hours. It is like buying a car, you walk out of the dealership and whether you got a fair deal or not, you always feel like they didn't give you the best deal, but you still have to drive to work each day.
Don't let George Lucas sway your decision, if it will bring you the slightest more enjoyment then what you have now, buy it, if you don't think it will, then pass.
