I am lucky 'cos here in the UK the original non slip rulers were invented: http://www.creativegrids.com/ I don't know if you can get them over the pond or what price they would be but to me they are impressive and do work. The built in non slip points on the under side really work and for me I love their clear Black/White markings.
