I agree the desirable "blue chip" type milsurps aren't going to get any cheaper.
The exception of course would be if the economy continues to plummet and average collectors find themselves needing something to pay the mortgage rather than having huge, luxurious gun collections.
Even then, there are only so many prime examples of the really iconic milsurps still in rotation. I recall when getting a nice German K98 8mm was cheap and easy. Now matching guns are a fortune!
I have only recently developed an apprecation for Swiss K31s and the excellent rounds they fire. I have never had an addictive personality for substances, but I do have a severe problem with guns. Oh well, here I go again!
