Source for finger drum pads?

Hi I am wondering if anyone has seen small finger drum pads individually for sale. Looking for something like the pads on this unit: http://excessiverecordsdjshop.blogspot.com/2010/06/m-audio-trigger-finger-drum-pad-control.html

Not exactly what you're looking for, but Spikenzie has a way to build your own using any materials you want: http://www.spikenzielabs.com/SpikenzieLabs/DrumKitKit.html

Yeah that's what I will do if I can't find anything else. I just received a shipment of those piezo pads to try now.
