Chuck:
Each to his own. But ANY decent double that has been re-cased is immediately off my consideration list. And not just for the refreshed colours. I've seen far too many cooked to the point of brittleness... even by shops which should know better. I can only imagine the first dozen results by a rank amateur.
I've also spent a good deal of my life -- and far too much time -- reversing the starry-eyed efforts of hobbyists. The metallurgical destruction of a fine double's key bits makes me cringe.

But as always, your words ring with wisdom regarding "chunks of steel" doubles. I respect your perspective.
