Since you have an Accuquilt you know how heavy it is. If you have a place for it permanently - the electric could work.
The Alto is as advertised, but if you can't leave it set up, it's heavier and bulkier than the Go to move around. I almost dropped one on my foot. I don't have room for it to be set up at all times.
The ruler type cutters could also be an answer - they don't weigh much to store and move.
