There are cheap GC (gas chromatograph) ovens on eBay. They are
well-insulated and give you fast, precise temperature control. Some of
them are designed with a liquid nitrogen input for cooling. Otherwise,
you can use dry ice. I saw one mentioned on one of the mailing lists I
read, maybe this one, a few months ago. I meant to buy one, but got
side-tracked. Unfortunately, I can no longer recall the brand.
