fwiw, I bought a four-pack from AIH @$58/per, delivered last summer, each with a package of fresh o-rings.
Not great but not horrible (and way cheaper than used kegs at my lhbs, I confess).
Three were in excellent shape, one had a wedge dent right on the upper seam.
Still surprised that one doesn't leak, but all four have done just fine...
Cheers!
