On that list the only two I've used is the Ranco and Herpstat.

Did the Ranco work? Yes

Was I happy with how it worked?

Not when it came to heating a rack. It does seem to work well in my incubator, but since it was designed for wafer heating elements the Ranco is a big step up for it.

Granted for me it was not just a $20 price difference when I was choosing as I got a Raw unit and wired it myself.

On to the Herpstat I have to add when I got my first I did the Herpstat Pro. For my racks and other enclosures I will only buy Herpstat now!
