Porky over at Porky's Expanseposted a couple of weeks ago asking if anyone knew of any masterlists for alternative minis suitable for GW games. There doesn't seem to be anything out there, but I do have a loads of links I compiled for minis that would be good for Necromunda or Inquisimunda so I'm going to dump a load of them here, maybe they will be useful as guardsmen or cultists.
