I just picked up 5 from these guys locally last week. I was talking to one about shipping through the Midwest; he said that one guy driving in from Omaha asked for a discount since he was making the drive, so he gave him a pallet (25) and 5 additional kegs free. I know it's a bit of a drive, but it may be worth it for a free $100 worth of kegs.
Oh, and the kegs looked to be in pretty good condition. Dirty, of course, but in the pack of 6 that the guy brought when we met, 5 of them were dent free and held pressure.
