A buddy of mine installed a new 7 Touch Gen 3 two weeks ago, purchased from David at Shut-up-and-fish. But, I now understand it is the only size currently shipping for some unknown reason.
Having two gen 2 units, I definitely like the Gen 3 better. Not sure it is any faster but, the extra buttons are really nice.

One thing we learned is that you need to do a screen calibration that is not in the installation manual. Simple to do but, highly recommend doing it
