I have the Accuquilt Go and I love it! I was on the fence for several months and now am so glad I got it. It's really fun to use and makes perfect cuts!
One reason I was on the fence was the cost of the cutter and the dies but it's really worth it to me. I have some basic dies- squares, triangles, and a 2 inch binding die. Really enjoying the precision and am making nicer blocks. The cutter is very easy to use and I have the crank.
One thing- the crank is great if you have no problems with your arms, wrists, etc. It cranks easily but if I had physical limitations I would get the electric Go.
The only con I can think of is the cost and I no longer think that, given how nice the system is.
Hope this helps!
