I have arthritis and using the Go isn't an option as I can't even get the hand crank to turn.
I have the Alto's QuiltCut2 and use it so often it almost lives on my cutting table. Yes it only does straight cuts, but at the different angles it is very versatile.
I have an old Third Hand. This was essentially a C style clamp and a rotating cutting board together. The clamp centered whatever template I wanted to cut, while I cut the template turning the mat. Since I found the local plastics company to cut any template I want, I can do curve cutting just great! Though, due to the arthritis I can only cut 2-4 layers of material at a time. Not sure it is made anymore, but got it from a Mr Quilt online years ago.
