I thought I'd give Craigslist one last try. I put a tool up, gave all
the specs, price, my phone number, said I had a couple photos, etc. I
also posted, at the end, that spammers and scammers should save their
breath.

It has been up about three hours. I just got my first scammer,
supposedly up in Vianna, VA, but unable to write English really
coherently. He wants me to take a cashier's check, to which he'll add
50 bucks for my inconvenience. Is "inconvenience" another word for
getting screwed out of money?

I emailed him back, telling him to check the notes on scammers at the
end of the ad.

I probably should have agreed to the deal, waited until his agent
showed up, and hammered the **** out of him just for practice. Except
the agent is probably some DC doofus without a real idea of what's
going on.
