Had it for 2 Le Mans trips and it's really pretty good.
I opted for the one that attaches to a big butane bottle. A 3.9kg Calor gas cylinder fits well ( same screw fit as the US ).
I have 2 burners - but in reality you only need one - putting both on is scalding hot.

I've got a Coleman dual fuel dual burner stove so I don't need to buy a burner - I can run the system on unleaded and it doesn't involve lugging gas around as space is always a problem!! I'm seriously tempted by this....
