We have a couple from WTB Binder Germany
(http://www.binder-world.com/englisch/englisch.html). We found them
technically better and still better priced than Forma, Sanyo etc.

The temperature uniformity is not a problem in forced air circulation
unit. Normally the culture can withstand +/- 1 degree without any

Given a choice a unit with heating cycle is any day better, even if
you need to use it few times a year.
