Large size incubator

Hi Guys, I currently use an igloo cooler to incubate my eggs, but it only holds 5 shoe boxes or so. I can't fill up my garage with 6x 120qt coolers! Next season I'm going to have almost 30 females going, and want to prepare ahead of time.

Does anyone have a good source or recommendations on larger incubators? Something that can hold 10, 20, or 30 clutches?

You can build your own out of an old fridge, mine hold 27 egg boxes at once.

Or you can buy one

Anyone use the Hotbox/C Serpent incubator? I have one of their racks and the quality is good. Do their incubators hold up?
