In reply to Dan_S: do you really need it? i took my primus omnifuel on 2 overnight trips and a 5 night trip, using it at least 2-3 times a day with dirty fuel (BBQ lighter fluid i think) without having to replace or service anything. i did clean it regularly though.
are you going for a long trip or going to be in a situation where your going to be relying on only one stove? if not maybe forget the service kit and bodge any repairs needed (probably none if its as robust as the omnifuel in my experience).
