I LOVE my Vitamix, and I use it at least once a day (usually more than that).
The one on QVC looks good (the only thing I wonder about is the container, as the handle looks different from what I have--mine is rubber coated). AND you can get it in red! (If you buy the red option from Vitamix, it costs something like $50 extra).
QVC has a wonderful, no hassle return policy as well, so you can try it for 30 days, and if you don't like it, send it back for a refund.
Go for it!
