Trying to outfit a couple bikes I bought a couple used cranksets off eBay. In the first one the seller said "there was lots of good miles left." Maybe he meant on the cranks. The chainrings are worn beyond where any reasonable person would consider using them. New rings will bring the cost over a new set. On the second crankset the crank/BB attachment bolts are missing. I'm awaiting the seller's response now. After this experience I doubt I would ever buy "used" gear again. Certainly not wear items.

Used items are not always a bad buy, but as you found out the hard way - have to be very careful of what you are getting.
I've bought some parts that were a bit substandard, and had some parts that FAR exceeded my expectations. I've gotten better at asking questions on what I am looking for and being patient if the right picture or answer isn't there.
I too am leery of buying wear items on E-Bay. If I'm looking at Cranks I'll wait for NOS, or new bike take offs, or something similar. Not perfect by any means, but gives me a starting point to know what to expect. The things I WON'T buy off E-Bay - Helmets, Shoes, Chains, Cassettes (unless new), Chain Rings (Same as cassettes), and tires (again same as cassettes and rings).
For the first set of cranks... check e-bay again, often there are chainring sets that go up that are new, just not the latest stuff. Unless you need all of Shimano's shifting pins, they might work for you. Or just check the mail order blow-outs - often that's the supply for a bunch of those E-Bay sellers.
Good luck on those cranks - hope the seller makes everything ok.
