I'm trying to estimate what it would cost to automate burner control for my new brew trailer. I'm currently out of work so this will be saved for future reference unless the sources are cheap enough. It seems that ebay can supply dual intermittent solenoid valves at a decent price but not Love controllers, decent thermocouples, or compatible spark modules for the Honeywell solenoids. Where are you guys finding these parts without losing a limb?
