 Uses piezoelectric static/dynamic friction motors.  The New Focus 8095 would probably be my choice for fine positioning, roll, pitch, and z in particular.  These stages are low profile, very stable, and very precise.  Some disadvantages are that they have relatively short lives compared to conventional motors and that they might be more expensive due to more limited availability compared to more conventional motors.  As of 2012 at auction they go for about $100 for a used 1" travel unit.  Controllers appear much less often but go from $50-200 for both "network" (computer controlled) and regular varieties.

 ===== DynaOptic =====

 Makes some actuators that look to be a little smaller than the Newport 860A.  Maybe stepper motors?  Haven't arrived yet.  I got a few for $40 each, a foreign seller was asking $100 each for the same units.

 The "normal" Newport stages are very nice but also tend to be the most expensive.
