machinequilter

I am currently looking to purchase a machine quilting frame. I have been looking at the Hinterberg Original or the SuperQuilter Proflex. My requirements are that I can operate it sitting down (I'm in a wheelchair), that it can be taken apart for storage easily as I do not have enough room to keep it up all of the time, and that I can use it with my Juki TL-98Q or my Janome MC11000. Also, that it doesn't cost and arm and leg to purchase. I would like to hear feedback, both pros and cons, on either of these frames or suggestions on others. I have looked at the frames that you use on a tabletop but those don't seem like what I want. I look forward to all of your feedback!
