Which Thermal Cycler

[Christian Beltinger]

We're looking to by a new thermal cycler and we're not sure who is the
best.  Currently, we are trying a Perkin Elmer 9600 demo and are wondering
what other companies manufacture reliable, compressor based machines. 
Ideally, we want something that can handle microtiter plates, has multiple
blocks, and a heated lid.  Maybe it doesn't exist.

If anyone knows of such a cycler and who might distribute it in the
Philadelphia area, we'd appreciate your help.

Thanks
