You mean there are still shade tree mechanics?
This is good advice, if you can spare the time. It results in a much more charming collection, and makes it look like you’ve been swinging wrenches all your life. My personal collection is like this, although it came from my grandpa rather than a flea market. I really should replace it with a full Bahco set, what with the discounts I get, but its charm is such that I can’t bring myself to it.
Speaking of discounts, couldn’t you get something at work? I assume you deal with one of the major industrial supply houses, the guys who come on board with hoses, fittings, fasteners, sealants and all that. They usually have decent quality if not name brand tools in their catalogues. The quality might be surplus to your needs, but there’s a great pleasure in working with great tools.
Edit: to illustrate my point about street cred, here’s my personal grab kit next to the one i use at work.
