Chester do the Champion 20V at £815 and Warco the WM16 at £998, both including VAT. Both look very similar to the Toolco VM30 which is listed on the Toolco website at £930 inc VAT.
The immediate differences as I see it, in addition to the price variations, is that the Warco machine has a 600W motor and weighs in at 103kg, the Toolco also has a 600W motor but weighs 115kg, whereas the Chester has a 1 HP motor or I guess 750W, and weighs 113kg.
So I guess on the basis of price, motor size and weight, at the moment the Chester machine would represent good value.
Just my thoughts!
