>>BUT, for a unit with a price tag over $550 in my opinion there should be a digital thermostat built in... Not a same waffle with the thumb screw that is also used on the $45 hovabator!
Yeah, I've seen that model up close. At the zoo I work for we have one of those in my building [Small Mammal and Reptile House] although we haven't used it yet [not breeding anything currently]. I can see with that circuit board thingie that maybe it's a slightly more high tech temperature control while still using the wafer thermostat. Actually the wafer might be a back up to the circuit board thingie. At any rate though, we've hatched out stuff for years using plain old Hovabators and of course plenty of hobbyists and even professionals have used them to great success. It's hard to argue with cheap and effective. If you don't trust your Hovabator wafer thermostat you can always do what a lot of guys do and hook your power supply up to a second thermostat set to shut the whole thing down if your wafer fails and causes the incubator to overheat. Me, I'll stick with my Hovabator.
