the pendants on the site require a second printer port and a small card that the pendant plugs into. You can do this with a smooth stepper. I know, because I have one (the longer skinny one) running on a smooth stepper.
with a smooth stepper, you still require a BOB. I personally love the C11g board. It has the relays built into it and just about everything else you could want. All right there. I use that board alot. Its a bit larger then the standard c11 board, but that is because of all the other features involved with it.
Wirering the geckos should be easy as pie.
