I would price shop on eBay before committing to purchasing everything from Auber. I purchased a lot of parts from Auber that I could have purchased for much cheaper on eBay, and we are talking about the same exact part, not a substitution. Additionally, you can find NOS Crydom SSRs for the same price as made in China specials if you are patient. You want a Crydom model D2425 or D2440 SSR depending on what wattage (the letter D means that it accepts a control voltage that is between 3 and 32 VDC). I also found NOS made in Japan electromechanical relays for less than the price of the made in China specials sold by Auber. I did pay more for my PID, but it is a American made Red Lion T48 that costs $200.00 retail. It paid $69.00 shipping included, and the PID was truly new-in-box when it arrived at my doorstep.
