There are a few companies - one is quilt-ez for stylus -
http://www.quilt-ez.com/9-stylus they have ones that other companies do not!
Found these folks -

Hope this is helpful -
have had a Megaquilter and inspira quilting frame for over a year. Found laser on templates too hard to follow and have been investigating these items to replace laser tracer which is no longer working. Please keep me posted - going to order stylus and a board this week. Thanks
