After trying all the brands at machine shows for 2 years, decided on the Innova 18" on a 12' frame with the basic stitch regulator. It is a wonderful machine and very easy to maintain. I do only free motion quilting but still wish I had gotten the 22" just to roll a little less often. If you want a computer system, get the 26". Their service is a phone call away. I have only had to call twice for operator error issues and were resolved in a friendly helpful way.
Be sure wherever you buy to get some classes in the deal. If you are totally new to longarming, there is a learning curve. Even with that, it is so much fun.
