If you can find a speed regulator like is used with long arm machines, you can presset the speed you like, and then just push a button to start or stop. I have one attached to my Elna--it plugs in instead of the foot control, so must be compatible. Mine was a Grace model and only cost $50 at ebay. I love it cause it keeps my stitches so even. Otherwise, a machine with stop/start button is my next suggestion. Have a look at the Brother models--many of them have this. The button is in front of the needle, so you should have no problems.
