I've had a couple of years flying piston, Basler-67 and South African -65AR versions of the DC3 (and the Basler -45 demonstrator).
SA -65AR MTOW 29,000lbs, Basler -67 MTOW 28,750lb, piston MTOW 26,900lbs
IMHO the Basler is the better aircraft, as it is totally remanufactured, whereas the South African aircraft are just conversions.
