the best vacuum ovens/cheap sources

[ohcannadah]

finally got my 1kg extractor have figured out how to extract passively . But now I have too much material to run in my vac chamber and hate leaving it unattended while waiting for each 50 gram slab to purge. I've been toying with the idea of a vacuum oven but haven't found any to fit my budget yet. Are there any sources for used lab equipment ? What temps give the best results? Anyone have a small used oven for sale working of course.
