Build it up to break it down again

So here are the bits I've bought already

Xylotex 3 axis system kit with 425Oz/in stepper motors

enco 12' of 1/2" acme rod 8 matching nuts

thebigbearingstore.com 6 1/2" 2 bolt pillow block bearings 8 1/2" shaft collars

Home Depot Tons of bolts, nuts, washers, bits and doodads. 20' of galvanized steel u-channel (not really sure what to call this stuff) specialized u-channel bolts, nuts and spacers aluminum angle iron 1/2" black pipe for x axis

Don't remember.com lovejoy couplers for motor shaft to acme rod

As far as buying things goes, I think I might be mostly done. I can foresee buying drawer slides for the z axis, a trim router, and the black piping for the y axis I might need to buy some more skate bearings at some time...who knows...
