I have the accuquilt go. It's ok. I don't know if I'd buy it again. I cut a bunch of 6.5" blocks, making sure the grain was correct. Some are about 1/16" off on one side. Probably no worse than if I rotary cut but I want them to be better than rotary cut. I have the 2.5" strip die and it's a tad bit narrow as well (measurements were all with my olfa rulers). I did have to smooth out the fabric doing the strips because it sort of scootched down as it was rolling through but that wasn't a big deal at all. But my biggest issue is that I have a bum elbow and it is really hard for me to crank the Go (this was with 2 layers of regular cotton fabric). I can do it but I pay later with pain in my neck and shoulder (and subsequently, headaches). So I have to pace myself-only a few cuts a day.
I have the small rag die too that I'm planning to use with flannel so I may have dh do all those cuts for me.
