I have found Faeth Aircraft in CA to be the best on prices for salvage yards. Sometimes less than half the price and very good folks to deal with.
They even trusted me to mail them a check after they shipped the parts.
I did not want them to pay the costs of taking my visa card after they gave me a great deal on parts. They told me to send the check and the parts were on the way, got my parts before they got my check due to the weekend.
