Looks like the heavy cast iron pan in the bottom.
Doesn't seem very used.
I'd consider it at $80. Maybe bring a propane tank and test the burner.
Kinda depends on how tight your $ is, how certain you are about wanting a gas smoker like that, and how much space you've got for smokers, but this would let you test the waters at a lower price.
I've got 2 of those smokers and I'm real happy with them.
