Notes:

Kepro Circuit Systems, Inc. (800-325-3878) offers a cheap negative acting 
dry film photo resist copper clad.  The development solution is a water 
based sodium carbonate (none of that nasty solvent stuff).

I've had good luck with negative, 1:1, artwork on a laserprint 
transparency.  One line between pin resolution.

For great precision mechanical components of all types: Winfred M. Berg, 
Inc.  (516-599-5010).  They have this real neat 3-D (x-y-z) belt and 
sprocket product.
