I'm thinking about getting these, but I really don't care to have anything done after 1946 when Curley was no longer able to perform. Most of the shorts after that were just remakes of the ones Curley was originally in. Shemp is a just okay substitute and Joe Besser was contract player forced on Moe and Larry. Curly Joe DeRita was at least picked by Larry and Moe.
I agree that the Curly episodes are superior to the others. But I'm going for the entire collection anyway. The audio and video quality is excellent.
