The PPSH has an appeal to me the others do not. I've not enough interest in stens, uzis, mac's to buy one. I seen one for 10 or 11k can't remember, but the ad was several years old.
The cheap ammo seals the deal, but it isn't the only reason.
About the only other gun I would consider is an Mp40. I seen two on gunbroker for 9k each a week or two ago.
Thanks for the advice.
