Don't frown just yet, but if you have spare GW's left over from any GG you have built with sword and board and you have some green stuff...
Skellies. just add a simple GS brestplate and shoulder pads should do just fine. otherwise, combine any pare axes you have, chop the head off one, leaving the handle and the "stick" bit and pin it to another full axe, bit of work to position the arm's and voila, cheaper GG with GW's.
Hope this is workable for ya Chris!
