Most of those materials are reverse engineer-able, though. This has a significant impact on the big manufacturer's bottom lines... they derive most of their profit from materials, just like regular printers.
You can probably get a spec-sheet for their proprietary materials if you ask. You might have to reverse-engineer cartridges with security features though.
The Fab@Home guys are trying out various different materials, since their syringe-based extruder allows more flexibility than the RepRap.

I'll just leave this here: http://open3dp.me.washington.edu/

See how cheap that is? Crazy...

As far as cheap materials go, it doesn't get much cheaper than garbage plastic.

Or you could just go here (this is my old startup): http://marketplace.cloudfab.com/fab_facts (click through for every datasheet on every machine and material)
