I had the 6600, then the red 7700 and now the 8900. The red 7700 wasn't my favorite. It did have issues, and they have now come out with the beige version under the New Home brand; it is available through direct sales (as opposed to only through dealers). I am a lot happier with the 8900, but would have been happy with the 8200 as well. If you can afford to go to the 8200/8900 I would.
