If you have the 820 on the Bernina frame it is a very nice set-up. I've seen it working with the computer to stitch out designs, superb however I can't imagine moving it every time you want to just piece. The 820 is a HEAVY sucker! If getting another machine for sewing isn't an option, I would look at maybe a rolling microwave cart? If you had something with wheels about the same height as the frame, you could maybe transfer it with the wheels to your sewing cabinet?
