It's a good friend, Kevin Struss. He has been in the hobby for a long time, is well respected and extremely knowledgable, and he and I talk on the phone often. Before I became a card junkie (and many times still) I call(ed) Kevin to bounce card and hobby stuff off of him. He started advertising on Net54baseball.com recently as he has been buying and selling some cards. He is also a collector and a valued board member. I put Kevin in the upper echelon of knowledge in the hobby and would give him my "gold stamp" of approval.
best regards
