Ok, I got needles today and tried her out. This is the first time I've ever used a knee-majig. I had to adjust the tension, of course. Wasn't too bad. It feeds the fabric really really well! Um, I was expecting it to be a little bit faster, but that's ok with me. The only real complaint I have is that I release my leg but the needle keeps going. I think I might have a loose belt or something.
