I also have shoulder problems (will have shoulder replacement surgery this summer) and I use a woodworkers clamp to hold my rulers while cutting because I can't take the pain in my shoulder when I try to hold the rulers. I got the GO about 3 weeks ago and really like it. I turn the handle with my right hand. I read on here that it helps to have the cutter low, so I use a table that is the height of my sewing cabinet.
