A visit to my LQS last Saturday resulted in the purchase of the best cutting ruler I have used to date.
Quilters Select - the back side is coated with a smooth but grippy surface and it will not slide on the fabric at all!
I also bought the Quilters Select cutting board - it has a dark side and a light side that will help my aging eyesight.
quiltersselect.com - I think she said it was by Alex Anderson?
