Some time ago there was a guy on signs 101 selling a substrate cutter. it was for light duty like foam board, coroplast. 1 mil pvc and 3 mil pvc. for a few hundred bucks. does any one have his website or name please and thanks. i have used fletcher and other bigger brands and i am not over welmed by them. they are good for light substrate and die bond but a panel saw or a track saw works better. My budget is also tight. for 250 i can get a grizzly track saw. if i can get the substrate cutter i am good.
