I don't believe I've found a bigger one than myself, I've got 2-20 (never managed to get hold of 1), the Rehydration of Violence LP and I think it's 31 and 33, never every heard the ones for 20 to 30, they never came into the local shop and I couldn't be arsed to hunt for them anymore. What other stuff do you like? Ever and Area 51 fan? What about Hardcore Mafia?
