I thought about building my own. I have access to plenty of shot mini fridges. I dunno, maybe I don't give myself enough credit, but I worry about building my own and all going to hell and being left without a reliable backup. I have plenty of supplies laying around to build my own, but I was hoping to get a factory built one where I don't have to tweak anymore. Just set the temp and walk away, if you get my drift. I might end up building a backup incubator out of a mini fridge and giving it a few test runs first to have just in case my main incubator fails me.
