Burnsie,
You are correct in putting those four among the top and I can think of others like a Dale Dye, a Brandon Stahl, a Jack Kemph, and a slew of others. I sometimes hate to mention names because I know I leave some out. I used to trade every once in a while to get something I really wanted. Everything I have now I really like and want to keep so trading is no longer an option. Consequently having any, other than the ones I currently have, is not very likely at present. I still like to look though.
