It took quite a while for the "Smithsonian grade" Samco had to sell out at a price compairable to SOG. And they had them in stock through an election and big gun ban threat over the Conn. shooting. Even the Chinese rifles are still available in certain retail outlets, the market as a whole is saturated.
I can understand the happy joy joy feeling in getting a "new" surplus gun also. But, realistically I've seen just as nice examples on the private market, for less. I've even seen the less common M59 for less money. An M59/66 is not like it's an overly rare or uncommon variant, they are almost as easy to find as a Type 56 Chinese stamped Norinco.
It's hard to justify a retail fixed stone & mortar store price based on auction prices, also it's not a fair comparison, like judging Ebay vs. Target or Amazon. From a buyers stand point, 430+ all the bla bla for a common SKS, when one could buy privatly cheaper or cough up another 100-125 or so and get an Ak or maybe a cheapy entry level AR doesn't make much sense. Again, especially, when some retailers still have the Chinese still available, for less money. Put the price, say 375-395, then the market would light up.
