Glen,

We purchased a Supraspeed approx. 7 years ago (shortly after their 
introduction) and had tons of problems, everything from weekly open 
jumper and sensor faults to replacement of the entire refrigeration 
system as well as the rotor containment shell.  It has been working 
much more reliably lately although the coating on the walls surrounding 
the rotor is flaking off and the service rep asked me what we did to it 
(we did nothing, just poor design).  I would expect that they have 
worked out many of the problems we encountered but, based on my 
experience, I could never recommend the purchase of one.

Best regards,
Brian
