I'm curious what you guys think something like this would be worth. I've teamed up with one of my coworkers to build a couple of prototypes specifically for this purpose. The box essentially has plugs for a PSU molex and wall outlet, with another set of plugs for your pump and PSU. When you turn on the PSU, a relay turns on the pump power and a pressure switch monitors the pump outlet pressure. If it doesn't reach a setpoint with "X" seconds, power to the PSU gets cut. Toying with putting some LEDs on to give a little feedback.

I'll emphasize it's just a prototype we've made and we don't currently have any plans for production. More of a "gee, wouldn't it be neat to have. . ." sort of thing.

Any thoughts? Sound like something people would be willing to buy? Priciest part is the pressure switch, which is ~$10 ea in quantity. Hand-made units would probably cost ~$40, give or take.
