The colchester is much bigger and powerful as the warco. 13*30" vs 10*22" and the weight ist at least 6*, the warco has a small 1,2kW Motor, the colchester at least 4kW.
Maybe, I can't see it on the pictures, it has a removable bedbridge without this you can
turn much larger parts who have a bigger diametre than 13" but must be short in length.
