I get mine from Second Chance Games in England. http://www.secondchancegames.com/I suppose it's a bit too early to hope for a Europe-based online store to offer these... (MMP's S&H is about $22 for $38 of products, I'd like to find something slightly cheaper...)
Their MMP page is http://www.secondchancegames.com/index.php/component/virtuemart/manufacturer/advanced-squad-leader-mmp-1.
They don't have it yet, but they usually have it sent to me within a month of WO.
