Don:
I've heard that from other CJ owners,,,Yak guys too, but I'm just partial to 1340's and lots of sheet metal around me! Never have done any ACM with Eastern Bloc a/c but have no reason to doubt what you've said.
RE: prices....like the guy said when we bought ours "They aren't makin' any more of these and they will always be in demand." Smartest investment we ever made, except that I just can't bear the thought of selling it!
