There's a couple of yahoo digests for the Innova machines. I have the 26" on a frame and love it. The customer service is top notch too if ever you need them.......365/24/7. The folks on these digests are very helpful too so might be nice if you joined them as I know there's a couple of them with the sitdown machines who have had them for just a short time so lots of questions put out by them.
