century graphic is guaranteed to have a graflok back, but it was also the cheaper version made out of some composite stuff, sort of plastic, not wood like the higher end ones...I found a nice Crown 2 1/4 on ebay a coupla years ago at a good price, has the graflok and a good lens/shutter and a body release.

But I'm a snob. For picture taking, a Century is an excellent camera.

KEH has a 2 1/4 Crown right now for $189 http://www.keh.com/Camera/format-Lar...c=80197&r=WG&f
