Well the less guns other people buy, the more for me! Apparently I'm buying every sks there is lately, lol.
Actually, if it's JUST a stock condition issue, then 400 isn't bad. One nice thing about new production guns, is that very little is serialed. No serialed triggers, AK mags, or receiver covers. So if its had stuff changed, you're not losing much value.
One thing to check....the serial of the gun. If it's an 88 model year...that's rare and desireable. Hell I'd even have you buy it for me if it's an 88 and you don't want it. The 93 and 94 sporters are the really common ones.
