OK Here is the deal on the Yugo SKS.
Many are already here in the country, FYI I have an very impressive example in my gunsafe this very moment.
Interordnance.com has these right now for $250-$300
Classic arms has these right now for $250
Lew Horton has these from $250-$300
Cetury International arms is on the verge of a very large shipment. They will then supply aimsurplus.com, SOG etc.... These will cost around $150-$200 although they may not be in the condition that the Interordnace guns are.
I overpaid a little for mine to support my local dealer who takes special care of me. I paid $320.00 +tax. Mine is in Brand New condition it has 99% blue, a mirror bore, a nicely grained stock, and no evidence of ever having been fired. The gas piston and tube is chromed however the bore is not. As stated the rifle comes with a grenade launcher, gas cutoff valve, flip up grenade sites, either phosphorus, or tritium nite sites(mine has the phosphorus and they still work), and a rubber buttpad with a hole for the cleaning kit. They also come with a sling, ammo pouch, oiler with pouch, and cleaning kit.
These are very nice collectors Items and I love mine so far although I have not had the chance to shoot it as yet.
edited to add that these come extremely well covered in cosmoline and I spent at least 2 1/2 hours resurrecting mine.
