Thanks for all the input................i bit the bullet and bought the 7700.....only because that is the machine I originally wanted and bought the 6600 instead. I know that this would be the only time I could buy the 7700 and the dealer gave me a great price on the one he had that he took to shows for demo's. He also threw in the table and gave me a refund on some expensive extras I had purchased for the 6600 that came with the 7700. I played with it all last night, and it does have most of the same features but in other ways, I think its better. I love it!
