I did this a couple of weeks ago. I keep one electronic pedal that works for most of the machines in the house, so I can switch off. It's great for the Applique and FMQ type stuff, or even just if you want a different feeling pedal. I had a guy come look at a machine this weekend too that said that the carbon pile resistor feet (like our button pedals) also reduce the amount of power to the machine as a whole, and the electronics don't do this as much. There -may- be a power gain (piercing power) as well with the machines, but I haven't tested enough yet.
