Pattyscorals on the big auction site has a couple of 4" claims listed, $50-$60. They are outside of Youngstown in Niles. Great people and some very nice coral also for sale. I bought a crocea a few months ago for $50 from them and its very healthy.
I would contact them without going through the auction, you would probably get a better price, and it would be worth the trip to check out the coral.
