Is there an advantage to use the PMDX-132 over the PMDX-125 for G203 drivers on a mill? I see the 132 is designed specifically to mate directly with the gecko drives which is nice but I think the 125 is a little more versatile, expandable which to me is nicer. Just comparing the features Im inclined to go for the 125 but Im concerned that the 132 is the 'gecko' BOB. Am I missing something?
