piezo translator/microelectrode drive

[Jonathan Carp]

I would like to hear from anyone with experience with a microelectrode
drive based on a high speed piezoelectric device mounted on a motorized
3D manipulator.  The same device appears to be sold by different vendors
(e.g., WPI has the MPM-10 Piezo Translator, and FST has the PM-10-1 one
axis piezo-translator with motorized micromanipulator).  Thanks in
advance for any advice you might have.
