 If you do proceed, tell me how you get along.

 Should make a decent base for CNC conversion, many 9x20's have been
 done. Should be able to make it at least as good as an ORAC since those
 are built on a Compact 8 clone and the 9x20 is a slightly larger copy.

I converted a mini mill using acetal nuts, they worked out great, cheap and no 
backlash.

I got the idea from this forum thread. 
http://bbs.homeshopmachinist.net/threads/43645-Making-Acetal-leadscrew-nuts-the-easy-way
A lot of good tips in that thread. 
Some pics of the mill
