as a lot of drivers now have the flat stove in a box
you may be interested that Argos do a good deal for the cylinders works out at nearly half truck stop price and if you dont use that many go halves with a mate
had a flat stove when they first came out and nearly barbecued myself after 2 weeks of use (bad pipework) went back to standup stove grew eyebrows back still have them 
I use mine daily, so thanks for that Hitch, will head down later. 
anyone near to Christchurch can pick four up for a fiver at G & T’s in highcliffe,or any branch in this area,used to be £1.00 each then started doing them in fours so price jumped 25p.
