I'm not sure if you can call it a "ranking"...it's just who spends the most dough...did you see the "While e3NiNe's on vacation can we spend a combined $1K in his honor?" posts? I think we hit something like $1200 that week.
I think e3Nine, Rabidmonk, Egg, and Hammy lead the pack here.
I'm just a small time collector.
I don't have a problem like these guys do.
