You might be able to one-hand the button pushing on the pendant, but I'd love to see a video of one handed MPG movement if you aren't near any of those handy "mounts." ;-) Depends on what you want out of a pendant I guess. I find the MPG wheel very handy except on long jogs. And Stuart has a machine that has some really long jogs possibly. Other than the MDI, that's where a joypad would come in really handy. I've been using the MPG heavily while I mapped out my vacuum hold down. I've been taking hold-down height measurements every inch the length of the hold down. One turn of the MPG wheel = 1.000" when the MPG distance knob is set to "x 100", and the Z axis moves .0001" for every MPG click at "x 1".
