Sorry folks if this is the wrong forum but I'm new here and FOG seems to be shut down. So, my question
to Festool users is: I seem to have read that there have been 4 iterations of the Rotex 90 and since I'm
a cheap shopper, I've been looking for used RO 90's and would like some explanation as to their differences,
if any. I find RO 90's and RO 90 DX's and RO 90 DX FEQ plus's, but no way to figure out if one has more
features than the other, or if it really matters.
