I agree with Sephie. The Creative Grids stripology ruler is pretty sturdy and will cut on half inch increments whereas the June Tailor only cuts on the 2 1/5 increments. IMO paying that much for a ruler, I would want one that would do more than a few cut sizes. Unless you do cut a lot of jelly roll strips or charm squares from the same fabric. I have the CG Stripology and Stripology Squared. I made a shadow box quilt and was able to cut all those 1 1/5 strips in no time with the Stripology. When I made my jelly roll rug, I cut all the strips using the Stripology. Easy peasy!!
Creative grids has videos on youtube describing how to use. Maybe check one of those to see which strip cutting ruler would work best for you.
