Jeanie: I hope this is not repetition.
Not only is an SKS rugged and dependable (mine is a Norinco), the ammo can still be delivered to your home at $.20/round, including shipping.
Some Yugos reportedly suffered from old corrosive ammo which damaged the gas tube/piston.
This is seldom mentioned about Yugos from other countries.
You can probably get your money back in the near future or possibly profit if you decide that the gun is not wanted and is in good condition.
My un-fired Norinco was a very good deal $200 last March because the seller wanted to get rid of his. They are listed much higher than that at any retail gun stores I've visited or the local gun show, and these other guns are in much worse condition, usually banged around. Mine was/is perfect. Two pawn shops here listed really good Yugos or Norincos for about $270 this summer. Prices have gone up in the last few months.
If you like the appearance of the gun (and its bore) in question, with no internal corrosion etc, then the price appears very reasonable. Will he let you shoot it nearby if you bring somebody along (as a female) and furnish the ammo?
And if you get your ammo at about $.20/round and try to sell it for that, you will have no problem. There are not only huge numbers of the SKS around, but also AKs and some Saigas for that caliber.
