I use a Minicraft drill and stand, similar to the Dremel units. It isn't 
very good - it's quite easy to break carbide drills. A friend of mine has a 
PCB dept. where he works and they have a rather old manual Excellon PCB 
drill. It looks as if it was originally *very* expensive and is *very* 
heavy. The drill comes up from underneath the PCB and a magnified image of 
the pad is shown on a screen. Someone at Southampton University was giving 
one of these away a few months ago, perhaps I should have taken it off his 
hands. 8-)
