Cheaper again but with larger initial outlay is a refillable gas bottle.
I went for a Safefill as its approved by Morrisons for filling at their autogas stations. Also being a lightweight construction is translucent so can see the liquid level.
Propane rather than butane so actually works in cold weather.
If you are tight on space they do a 5kg cylinder 390mm high, 310 diameter
My flogas propane 6kg, about 12 litres, cost £34 for a cylinder swap, autogas is about 90p to 105p per litre. Do the maths.
I found two free apps that show the location and price of outlets all over the uk and europe.
