Don't know about this machine, but I was able to try out an Easy Quilter at a quilt show and really, really liked it. The machine they used was the Janome 1600P (1600 stitches per minute). With this setup, you spray baste your quilt (which I like). Here is a link to the website:

I think it's a really nice alternative to the expensive longarm setups, and a great way to get started with FMQ. I sat down, the guy told me to "floor it", and I was immediately able to make flowers, etc. Fun, fun, fun!!!
p.s. It was the EasyQuilter 3 that I tried out at the quilt show. The tracking was really good. With large quilts, you would want to quilt in sections, but that is pretty easy to do by splitting the batting.
The big difference between this and most sitdown machines is that with the Easy Quilter you are moving the machine, not the quilt. I think that is always going to be easier.....
