Hi Jon
I have just bought a Warco WM250V-F at the Harrogate show last weekend, I was also down to a choice of DB10VS or the WM250, what made up my mind was the Chester machines were lacking in refinements i.e. no leadscrew telescopic cover(this seemed to have been removed judging by the brackets left on the machines, but could be retro-fitted, at a price of course!), no power X feed, & delivery charges.
Warco's WM250 V-F included all of the above at no extra cost so it was a simple decision,but the choice is yours.
