I recently bought the Bernina Q-20 sitdown. It comes with a Koala table with two extensions as part of the package. The reasons I selected this model are the built-in stitch regulator sensor in the base of the machine, it uses standard Bernina feet, and regular sewing machine needles, is easy to thread, and has a built-in bobbin winder. Since I already own Berninas, the learning curve on how to use the machine has been easy. I haven't done much with it yet, since I've only had it set up for a few weeks, but I plan to use the heck out of it soon since I'll be retiring (this was my retirement gift to myself!) Yes, it has no feed dogs, but I have other machines to do that - I got tired of stuffing larger quilts into my Bernina 750QE. Good luck!
