I bought the Janome 3160 for a class machine. One key feature was the included extension table. It's been great. I negotiated an after-tax price of $599 from a dealer in MA close to NH, where there is no tax. I also took an FMQ class with the machine and it performed wonderfully. Even though I'll use my 7700 at home for FMQ.
I have this same set up and love it! I used to have a Janome Gem but found I didn't like the 3/4 size. The 3160 weighs the same as the Gem but is full sized and has more features. Love it! I got mine from Brubaker's Sewing Center in PA. I have no connection - just a happy customer!
