ditto to the previous comments ... consider all in your decision!
As for the Janome 6600, I bought one a year ago and have been thrilled with it from the start.
I don't know where in Ontario you are ... the CNE opens Aug 17th and Janome has a large display with demo machines there for you to try. Also, there are always show specials/prices that are better than the day-to-day store pricings. I didn't go with any intent at even looking at machines, let alone purchasing as I was working at The EX. Although I had planned to start my research in the winter with a purchase this spring. Well, one day, I pretty much tripped over my dealer and just had a chat about what would be my next step up. Two days later, the deal was made!
If you're interested in more info about buying at The EX, send me a PM and I'll give you some extra tips and answer any of your questions.
