well i just bought one .its not just the actual tool, its the software the support and honestly its the geomtry of it. ya its half the price i paid for my cnc mach used but its cheaper the a 9k laser machine and does a better job theres no other way to cut dollartree foamboard with the paper on,yes you can use a laser cutter but notice the valley when it burns threw the paper it melts the foam back,this tool dosent have this problem, and the other people making something like it cant cut anything this thick. and its 3 times the price. easy to cut fan fold foam with a tile rotozip bit. but its wavy flimsy and cost more then dollar tree foamboard we use dollartree foamboard b/c it has the paper on it .its a surpior product i make rc airplane kits so i make them in large amounts, cutting them by hand is not a option. yes up front it seems like alot. but ive seen routerbits that cost more.
