I have purchased a couple of high speed air powered die grinders from 
<www.princessauto.com> .  They sell them 2 ways: individually (CAN $30.00) 
or as part of a kit with several bits and a plastic case ($70.00 Can).  I 
have not used them to drill PCB holes yet but they appear to have almost no 
run-out.  They spin FAST!

The high speed electric Dremel type tool I've used for drilling PC Boards 
over the past many years looks very similar to a Dremel but has a label 
that says "Metal Removal Corp".  It has sleeve bearings, NOT ball bearings 
and has exceptional run-out characteristics.
