Having overpaid for several 1930's purely mechanical pins I'd say about $150-200. I've paid a lot more for 30's machines but then I see people grabbing electro mechanical machines for far less. There's a recent thread about a guy who scored a 1930's electro mechanical machine for $100. Ones with ramps are definitely more desirable, as are EM's as opposed to purely mechanical. Check into the pre-war thread for more info.
