Be the ball!
You can't swing a beer without hitting an ebiab thread. I went through it, the research, threads I started, and the build. Looking back, I wonder if a single breaker power switch and potentiometer would have been enough for me. No temperature probe (pid wont work without it, and I don't use it anyways), simple, less expensive, and pure analog control. I suspect, admittedly possibly incorrectly, that with a little experience, decent temperature control can be created by using a potentiometer and pump. If you want to mash at exact temperatures, step mash, like building stuff, or are using multiple pots, etc...full controller like mine is for you. But if you brew like me just insulating a kettle, passively maintaining heat, than perhaps you dont need a pid. Thoughts? Ultimately I decided on having more options in the future, but looking back making a simple controller for super cheap might have been my best bet.
