I love my rotating mat I bought at the Jacksonville, FL quilt show a year ago - it is white and 24x18 with a mat that is removable and replaceable! The base it rotates on is large so when I'm working on the edges it doesn't tilt. I don't remember the name of it and since I'm not home, I can't go check. If anyone is interested, just post back and I'll look when I get home tomorrow.
