In reply to Agrius: I like my omnifuel and went for it over the MSR because it had the aluminium pump rather than plastic and the pot holders are excellent (toothed rather than just wire).
Running on diesel or paraffin is a pain in the ass as the jets block every time and priming canm be troublesome. Petrol or gas is brilliant (just don't light it on petrol in your tent!). Tough as anything, mine has been in my pack to the himalayas, andes, and all over the UK.
My fuel hose split this week but it is 6-7 years old and as I say, hasn't been especially well cared for (get's stuffed in my pack so squashed, chucked around, dropped, bashed etc).
Having had the recent issue with the fuel hose I would recommend one from a brand with good spares back-up. It will ALWAYS be days before a trip when you need a part!
I am a big fan of liquid fuels rather than gas, but as I say, avoid using diesel unless you really have to (which in teh UK and Europe you won't). In fact if you can get a stove that doesn't run on diesel for less money (and are not planning a trip to anywhere really odd) I would! You can even run them on benzine, available in chemists (some places anyway).
