Best Thermostat for Incubator?

[The Serpent Merchant]

The intro will only take a two prong cord, it doesn't have the grounding plug built in. Hardware stores sell adapters to turn a three prong into a two prong cord, but that isn't really recommended because it removes the grounding on the cord.

The grounding issue isn't that big of a deal really. It only pertains to metal racks, and there are other (honestly better) ways to ground a metal rack.
