http://www.dakkadakka.com/dakkaforum/posts/list/8.page JForum - http://www.jforum.net SW players. I've looked through the couple US based bitz suppliers I know of, and Ebay to no avail. Helmeted ones are out there, but the bare heads are no where to be found. They're much better than a large proportion of the SW heads, and while I need to try my hand at beard and hair sculpting, I'm hoping to find some of these. Anyone know a fairly reliable source? Preferably US based, but I'm starting to wonder if that may be asking too much.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5453340.page http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5453340.page GMT http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5453941.page http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5453941.page GMT http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5454123.page http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5454123.page GMT http://www.ebay.com/itm/WARHAMMER-BIN-BITS-CHAOS-MARAUDERS-35x-HEADS-/330871451189?pt=Games_US&hash=item4d0979ae35

Ebay search for "Warhammer Marauder Head" turns up several results. You're going to pay for some of the sets though. If you scroll down you can find the heads individually.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5454351.page http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5454351.page GMT http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5455163.page http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5455163.page GMT http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5455237.page http://www.dakkadakka.com/dakkaforum/posts/preList/517660/5455237.page GMT
