I have the 830 and love it. I'd really like to have one with a larger throat but they're out of my price range until I hit the lottery. Please don't waste money on the Fabu-motion thing--it sucks!!! I got one and used it maybe 3 hours. The area is too small and you spend all your time repositioning the quilt. The machine has tension sensing so you don't need a walking foot and you can do FMQ (well I can't yet) easily without that thing. The machine has so many features for the price that I'd get the same one again. I agree about service-the LQS where I got mine does the service and has classes for Viking users. Good luck on whatever you choose. I think that's a good price on a new Viking.
