Does the go cutter waste a lot of fabric? And do you have to purchase a lot of supplies for it? My lqs has an accucut they rent by the hour but the last time I was there they said no one had rented it yet and they were just figuring out how to use it. I thought about buying one a few years ago but it was cost prohibitive and so big. I didn't realize your go cutter was the same thing only smaller.
