Hi, I have a polymax, I also have a EX 30, in my opinion the EX 30 is much more enjoyable to use, so much more accurate, I spent hundreds of pounds on bearings, belts, condenser, bellows, clamps , rear tension-er lever ( only knob on original, pain doing lots of holes with) Hegner charges are daylight robbery old technology will go forever like a farm tractor, lovely bit of enginering, but give me a smooth modern quite car every time . I stack cut and do very fine detail cuts close together with the EX 30.
only my opinion. been a carpenter for over 50 years
