You know what, I've never ordered anything other than PAM from ProPoducts and I can't see if there's an order button I'm missing either :/. I assume to contact them to special order? Reptile basics and LLL both sell them as well. You do need to regulate it with a t-stat, but the claim (at least with the Proheat guys) is that it won't burn you/ the animal/catch fire even in the event of t-stat failure.
