I know this is an old thread, but worth bringing back up again regarding gas canisters.
I am positive I've made the point in the past about camping and caravan stores being cheaper than tackle shops.
This week I came back via my local George Sharman Camping and Caravan and decided to grab a couple of GoSysten canisters as I was passing.
£5.50 each compared to £5.99 or £6.99 in a couple of my local tackle shops.

Right for the anal out there, a list of canisters I have used and I think the best to worst, these are all Propane/butane/iso-butane.
Primus and GoSystem. They both will run until empty with no need to shake or warm. In winter they are my preference
Sunn Gas, I hadn't seen these anywhere except one of my local tackle shops, it did require a shake but worked until empty.
CADAC, will work, but in winter may need tipping on its side to completely empty.
Coleman, the premium name, yet the worst gas canister. Even in summer they need shaking or tipping on their side to empty. In winter they need heating up before you can get a decent burn out of them, even at almost new.
