I'm to cheap (frugal?) to splurge on the GO!
For me, I use the June Taylor ruler for cutting strips. It's 12"x12" with slots every 1/2". You just run your rotary cutter down the slot for the width you want and presto !, strips! If you want more than 1 strip, just leave the ruler in place and cut every 1 1/2" or 2" or 4", whatever. Goes pretty fast. I had all the strips for my Bargello cut in about 15 minutes.
