Really, the only places to find one of the factory folders are on the secondhand market (gun shows, the EE on here, or even other sites such as gunaddicts or firearms canada), as Ruger no longer produces these. Expect to pay a lot for one, as demand and scarcity have really driven the price of these up in recent years. I bought mine from a former CGN sponsoring dealer for around $300 back in '09, and it was in good, but definitely not great condition. In the last couple of years, I've seen the asking price for ones in much better shape than mine in the $400-500 range, and some as much as $600.
