MG725 is heavy, loud and the power selector is by far the worst pain in the *** I've ever seen on an impact. However, rotors don't break on the MG725 like they can and do on the 2135 and the end plates for the motor are steel, not aluminum like the 2135. 2235timax has a wear plate in the motor and the rotor part number is different, though I've yet to see one inside I'm assuming they fixed that issue. That said, myself I'd be looking real hard at the 2235timax....
