On Weaponeer's Forum, there is another potential for a Group Buy on MG42/34 belts again. The last buy was good for me as I got 10 belts for $50. There is no guarantee if the Belts will be WWII or post war. I received 7 WWI and 3 post war Belts, so I was a very "happy camper" with the buy. Some of the other guys got mostly post war belts.
If you are interested, here is a link to the thread: http://www.weaponeer.net/forum/forum_po ... =1144&PN=1
