inverse, 

Oh, and the going rate for a .50 AE Desert Eagle in "as new" or "once fired" condition with original box and papers is really only about $1300 with free shipping to the dealer of your choice.  If you price quality handguns these days, then that's not terribly out of line.  (And after all, with a Desert Eagle one does get a great example of Israeli engineering and technical know-how.)  And go check simpsonltd.com for what an old commercial or "surrendered once" (or twice) Luger pistol in nice condition costs now.  The old joke among gun traders is that back in 1873, a $20 gold piece could have bought you a shiny new .45 Colt Peacemaker revolver (aka Frontier Six Shooter in .44 caliber).  And you know what?  That same $20 gold piece could just about buy you a new one today.

Quality guns seldom depreciate in value, quite unlike the wheels you might happen to be driving just now.
