Old colonel:
I like your notion of of looking at the cost of a gun as "a rent payment".
I've been looking at guns online and found 30" barreled sidelocks, English, Spanish and Belgian, are scares as proverbial hens teeth, especially those with original barrels. Any number of sleeved guns out there, but I'll stay away from them. Some nice stuff out there. Most above my price range. Oh we'll, it's an
interesting search though.

The only constant in life is change.
