After a lot more digging around on the web, I found a few units that look quite good...
This one looks nice - almost like a prop from "Stargate" of something like that!

I have only a little experience with multi-fuels - my mate had one (Apex, I think?) that he used with kero and unleaded. Sometimes used to be a pain to get lit - plus you have to stuff around with petrol - not nice when you get it on your hands and them you have to eat...
Hmm... The more I look into it, the more I'm attracted to butane/propane - clean, simple, efficient and cheap... That multi-fuel I showed above can also run on butane, but used the (relatively) expensive screw-in type cannisters. I think there are adaptors out there that may do the job...
One of the best cheap butane solutions I can find, which might be worth a shot for the $$$, is this:

Comments?
