My best friend died a month ago - it was kinda like knock knock - I lost a husband that way and my present husband lost his wife same way - so the lesson is - live and dance. So I decided to throw caution to the wind and get the Horizon. Life is too short to be practical all the time. Somehow the name Horizon said it all :) Seriously I cannot see me getting another machine for a very long time, this machine has everything I want. The 6600 is a beautiful machine and I loved it so much when I bought it that I wrote a write up for my local shop and asked her to put it on her wall to tell people what a great purchase it had been for me. I cannot fault the 6600. I met a lot of women who bought one, and they all loved it.
