I was unsure if the mini-refrigerator I had would fit three tubs, so I was able to score this small 4.2 CU refrigerator for free at our local recycling station. I added two feet of 11" flex, created a window, and hooked up a Herpstat. Voila' my new incubator.
I went with substrateless incubation, which allowed me to fit the three tubs in nicely. Thanks goes to Lord Jackel and to the search function :D
