I was shopping craigslist and found one with a liner for ten bucks, but that would have been a hell of a drive to pick it up.
I did some research and found a Barrel place in Pittsburgh - Penn Barrel (been there since 1908 or something like that) - They sold me a reconditioned unlined drum for $30, worth the extra money for the reduced hassle. It was a little odd walking into the warehouse with my three year old and nearly two year old (I'm a teacher so it's daddy day care in the summer) The guys working there got a kick out of it, and my girls were amazed at the thousands of barrels they had stacked up.
