If I were looking for my first SKS in CA, my personal preference (in order) would be: Norinco 16" paratrooper, Russian, Romanian, standard Chinese (Norinco), Albanian, Yugoslavian. But, actual gun condition and price could easily change this order. I put the Yugo last because it lacks the Chrome-lined barrel, and I'm not too fond of the extra length (due to the grenade launcher/muzzle brake) and the grenade launcher sight. But an excellent condition Yugo is likely to be easier to find (since they were imported much more recently), and the ones I own (several) seem well made.
I don't doubt that people still occassionally find nice SKSs for $75-$150 or so, but this would be a very lucky find in CA (where our options in semi-auto rifles are much more limited than the rest of the country). It really depends on finding a seller who doesn't know the current market value of his/her rifle, or who is very impatient to sell it. Kind of like finding an original M1 carbine for $300 (I'm sure it happens once in awhile, but you could miss out on a lot of shooting while waiting and searching for such a deal). I'm a bargain hunter and always looking for good deals on guns, but unless you are willing to wait months or years for such a deal to come up, I wouldn't hold out for it. Think of it this way: If you buy a nice SKS for $250-$300 and take care of it, then if you come across one of the great deals others have mentioned, just buy it and you will almost certainly be able to sell either it or your original purchase for a profit (I think prices will continue to creep up - unless another bunch of SKSs are imported - and I've seen no indication that this is likely). Of course, if you are like me, it will just become another rifle added to your collection (can you have too many SKSs?).
I don't live near any Turners, but my guess is that if they were selling CA Yugos for $180-$200, they were probably "good" or maybe "very good" condition rather than "excellent" or "unissued." This isn't necessarily bad, but with a non-chromed Yugo, you have a good chance of barrel corrosion. And if they are currently out, I doubt they'll be getting many, if any more in (since I think the import/wholesale channel is pretty well depleated).
