Yep these parts are far from cheap. So you really need to make the right purchase. By all means look into them and maybe contact Crane. They were well aware of the problems and were supposed to correct them. If that's happened I don't know. Or if the sets your looking at are old or new. But for that kind of money I'd want to hear some answers. Good luck with the parts search. I'd love to have a set of Erson's myself. But I still have a long list of parts before them some $3k later. LOL it's only money right???
