B.A. Murry has been a dealer for many years. You'll find his ads in the old card periodicals and I'll guess he still does in the current magazines as well. He is a contributor to the almanacs and price guides as well. There is a guy who is similar with canadian issues as well, although I can't remember his exact ebay ID..mleeking or leeking, I believe, for Maury or Morrie Leeking. He helped me complete my canadian Garvey wantlist.
Sometimes you have to pay to get singles vs complete sets or for the more obscure stuff. He has nothing too unique for Garvey right now. Nothing I don't already have myself. However when it comes to really tough items like the FBI discs and stuff like that, just seeing them offered is a small miracle in itself, regardless of the price!
