Plans or Specs for a Super-Sturdy RepStrap

Does anybody have plans or specs to their super-sturdy RepStrap? I'm thinking of building a milling-capable machine for my high school, so any help would be grealy appreciated.

Have you looked at the jgro plans

and
Patrick Hood-Daniel's design for his machine?

What is your budget, and how big a machine do you want to make?

And have you considered just cnc-converting one of these

When it comes to the budget, I would like to get some funding from the school, and being a public school, that isn't much. I have parted with $800 on my Darwin, so I guess I am willing to do the same with the mill.

As far as the dimensions go, I would like to be able to mill a standard 4x4, so i guess at least 30" x 15" x 5". After that and it is just a bonus. However, I looked at Patrick Hood-Daniel's design, and it seems to me that one of the axes can be as long as the rod/channels will let it.

As long as backlash and such will let it, you mean.
