He has one left I think. You can buy them on epay or from a place like meredeth instruments. Depends on how much you wanna spend, and if you want assurance it'll work.
Nope I still have 7 modules available, and the prices are listed on the first post of this thread
I no longer have a power supply for them, but you can find one on eBay or through Meredith Instruments relatively easily. I would guess $50-$100 for a supply
