that's why i binned off gampinggaz and went over to calor the "benefit" of the small can for twice the price.....
go outdoors do them for £24 belive it or not , n if you have ccc membership you can get an extra 10% off that too , but yeh they are getting rediculous
i actually use the calor patio gas 5kg in the van with the quick release top, i did get a 3.9kg propane originally but thats a screw in regulator which i didn't like in the van so i use that on my gas cooker for outdoor use, the 5kg patio has 2 handles on top which balance my shelf on in the westy cupboard - i did lose a bit of space but it's cheap.
