I recently got the Simplicity Rotary cutting machine. It helps me make 2 1/2 inch strips for my jelly roll patterns. I'm not sure if that is what you are looking for or not.
I find the best prices at this on-line shop. I've seen it posted in this group before. It is www.ihavea-notion.com I ordered it last week and got it within two days. I've been using it every day to get my strips ready for this weekend.
