Hi Joe, You can expect to pay 40 to 50 dollars for a matched pair depending on the source. Singly you can find them for 18 to 20 dollars. I have personally never had a matched pair and have had good luck with NOS singles that I have found at hamfests. As long as you don't try to pair an obviously weak one with a real good one, you should be fine. 73, John, W4AWM
