Does anyone have experience with the new BioRad continuous elution
preparative electrophoresis device (Model 491 Prep Cell)?  BioRad claims that 
one can load 100 ng to 50 mg of protein for SDS or native gel electrophoresis
using their machine.  I would greatly appreciate hearing the pros and cons of
device, and also if there are other preparative electrophoresis machines
available.   Thanks very much.    
Apologies to all if this is a duplicate posting.
