Anyone know of where I can buy a propane burner to make my own firepit?

I have seen some table top fire pit's made from a wine barrel and wondered if anyone know's where I can get the burner and regulator without paying an arm and a leg. I have found what looks like multiple sites on the web but as I open them I realize it's the same people with a different name on each site. Any help would be appreciated.
Thank you
