Chops, the Nitros and the Miroku won't likely need a gunsmith in the time you've got left to shoot them.
I'd take either over an LC Smith that had cracks behind the lockplates, a Parker with a bolt through the head of the stock, or, a model 21 with loose lug/and or ribs.
Noticed plenty of the above over the years. Graded Bakers with normal stock dimensions get my vote.

Best,
Ted
