Nice Work with the Geo. Did you guys know Solid Works is having free 90 day trials of their modeling software? It is not bad, and a free download. Sort of fun and has tutorials, so if you wanted to model something up and could learn to use it in 90 days it would be free to do the CAD stuff. Here is where the download is:

On another note, I got a 10% paycut today and am going to have to put the controller on hold for at least a while. I will be paying close attention and would still love to photograph one for posterity and open sorcerers (just made that up) everywhere so don't count me out just yet.
