[URL="http://enigmaminiatures.com/"]Enigma Miniatures[/URL] produce ranges of 54 and 30mm scale models, and some busts and a rangeof scenery accessories liek treasure chests and the like. The actual size of the 30mm range seems to vary, my brothers have some which fit in well with GW miniatures but others seem too large going by the measurements on their website. The sculpt quality is very high.
