Attempted to buy an Op-Amp from Brian, but after a search, he couldn't find it. He refunded my money plus a little extra because he thought paypal was keeping the fee. He was an excellent communicator throughout the whole process, and I would not hesitate to do business with him in the future. I mean I just couldn't believe the amount of PMs he was sending me regarding a $9 purchase. He seems to be a stand-up guy, who takes his rep very seriously.
