Hi Jerry, just wondering if you ever tried anything from Grayhill? I'm also thinking of using their Gen 2 MMI for mobile machine control. Specifically the proportional joystick. Currently using an LC6 and XC21 combo, but the Grayhill option simplifies things substantially.

I looked at them for a project I was working on back in April but the ones I needed weren't released yet. They were the key pads with the encoder in the center.

Okay, thanks for the feedback Jerry. Not sure what we're going to do yet...
