There are a number of vendors out there who sell medium format folders, etc. that have been CLA'd. If you're open to former Soviet cameras, there's a vendor called Fedka -
He's actually in New York. There's another vendor who sells old Agfa and other german folders - Certo6 - . Give those two a look-see and you might find something you're interested in. The prices they have are not the cheapest, but their cameras are overhauled and ready to go. Anything you come across on Ebay as you've already seen is buyer beware.
