There're quite a few guys around here, I'm not far from where that guy is selling from, that just dump charcoal in the bottom and cook. Doesn't matter if there is a liner or not. I bought a barrel from a guy that makes "UDS'", he was surprised that I'd take the time to remove the liner. Plus the concept of a charcoal basket was just a waste of his time.
