Building my first rack, just need to add heat tape.

It looks great!

I have a Herpstat 1 and I love it. I think their cheapest thermostat that does two racks is the Herpstat 2 at $195, so it's not too expensive. Depending on how many racks you plan on having in the future, you may want to look at the Herpstat 4, as it does 4 zones and not that much more expensive at $339. The Vivarium Electronics VE-300X2 also does two racks, and it's the same price as the Herpstat 2.
