Yup I'm bored today so was wandering around and priced some components for a PID controller. If I could think of a possible use for a 4th unit I'd probably be ordering parts. $22.08 would have gotten me the PID, a TC, SSR and a heat sink shipped. I paid over twice that for my first PID alone! Would think with a bit of scrounging a guy could keep the costs to about $30 total.
