They are pretty pricey to have made. I did the layout in Express PCB. Their price is 2 (minimum qty.) for $87 including shipping. I'm sure they can be found for less, but we would need to have someone here that knows Eagle or some other layout package that supports gerber files redo the layout. The do it yourself method can be painful, but is least expensive. You would need raw pcb, etchant, and drills. Although if you don't have a drill press or dremel drill press it's not much fun either. Total cost this way maybe $20 for 1 plus $6 shipping for the drills. The factory made ones are really nice if you don't mind the cost.
