Since I wrote the original posting and have an Ericomp cycler, I should
relate my recent experience. I have tried the Idaho thermocycler and it is
AMAZINGLY fast. Because of the capillary tube and the extremely fast ramp
times, the buffer composition is quite different and needs to be
optimized. What worked for the Ericomp did not work for the Idaho cycler.
But once the reaction has been optimized for the Idaho, it worked very nicely.
For diagnostic procedures, I don't see how it can be beat.
The only thing that nags at me is the $3900 cost of the thermocycler.
The price is in line with other thermocyclers, but the design APPEARS
simple. I'm looking into building one myself. If anyone has experience or
is interested, please let me know.
