Tom, thanks for the always helpful information.  I may come back on to ask some further questions about your other points (although they are pretty self-explanatory) but wanted to follow up on this point.

I've known about microsteppers for a while, but I've never seen one on 
eBay or anywhere else that I hang out.  Are they possible to find 
without special connections in the T&F field?  What brands/models are 
good to look for?  Sounds like a very interesting gadget to play with, 
if I could find one.

Thanks,

John
