Still waiting for NAVL to deliver mine and the anticipation is killing me! I paid $5300 for an unmodded one and I consider it a pretty fair deal considering what they seem to be selling for lately. Without a doubt, all the Pinside IM posts have driven the price up and it still seems to be climbing, so I'm glad I bought when I did.
Sgtmax, good luck in your search. Part of the fun is the hunt and I think you can still find them in the $5300-5700 range unmodded.
