You can make your own. You'd need a router and a steady hand to do so, however, the ones from Circle Lord and Urban Elementz are especially nice. Keep in mind that buying them retail is quite costly - the Circle Lord boards run a little over $500 for a "king size" length. You do need a stylus - Circle Lord sells them as well, and gives really thorough instructions on how to attach them to the longarm. Keep in mind you've got to be skilled at lining them up, as many of them have trickier interlocks. There may also be more backtracking within them, as it's easier to land the backtracking *perfectly.*
