I have great luck using Glad Press and Seal on the bed of my machine. It sticks temporarily, and really helps the quilt to glide. Just be sure to remove it each day when you're done, otherwise you need to clean the sticky stuff off the bed of your machine.(with something like pledge). The only negative to this, for me, is that I need to peel it back for each bobbin change.
I have a supreme slider (which I bought from my sewing machine dealer- big bucks-$$$) which I hate. It rolls up and gets stuck under the quilt and I'm constantly stopping to keep from quilting it into the quilt.
