Does anyone have experience with Variable Reluctance Displacement Transducers 
(VRDTs)?  Morrissey appears to have used them extensively and they seem to have 
a number of advantages.  They are inexpensive and easy to fabricate (so Morrissey 
says).  They are sensitive and have a low impedance output so parasitic capacitance 
wouldn't be a problem.  

It's true that they do produce heat, of course.  Any other drawbacks?
