Have a friend that has the Altos and the one time I tried to use it, it felt weird but probably just takes some getting used to. However she loves it. If you are going to the show I would ask them (maybe during a slow time) to let you use it - take some old fq's with you. My mom does have the Go but she uses it mostly for the applique shapes. You can make a mistake when cutting strips/squares, etc. on that also. Your fabric really needs to be ironed before you cut it - I always do that so not an issue for me.
