I do work for free as this is just a hobby and I don't want to spend any $ if I don't have to. I think $50 is not likely unless I get real lucky. I would guess that over $500 is more to be expected for a useable unit.

JHannon - I am glad to hear that it has been useful for you but I am also wondering what you are using the reversed lense for as the book doesn't mention anything about it. Either a later edition of the book has more info or you came up with your own adaptation. Either way I am interested in what you did.
