i bought from the guy in danbury who posts that he has "thousands" for $22. Real nice kid,, they have a bunch. pretty good shape, no stickers, not too dirty. I replaced the o-rings, but the ones that came on them would have been fine if just soaked in some oxyclean or something. I took ones that were holding pressure, and he added pressure to some others that looked nice, so i could see if they were holding pressure, too. Unless he's changed, they are only selling plastic topped ones, as they still use the few metal lid ones they have, though i've been using them and they are fine for all intents and purposes.
