I have Olfas and love them, I also have the retractable Ablade one.
Check into Alto's Quick Cut (I think that is waht its called) They have a video on line. I am going to see it at the quilt show next week and plan on buying it if it's as good as they say (about $200.00). I love the AccuQuilt but it is so limited unless you have all the templates and that would run over $1000.00 and you still may not have what you need. I haven't heard anything on the Sissix yet. But doesn't that also need templates?t
