...is still only pittance.
When we're talking between an £8 expense per 1000 shots, or a £12* expense per 1000, I think that fussing over that cost is fairly irrelevant.
*About what a bottle of MAPP costs over here. Like I said, not a huge amount more.
If you don't want to stump up the extra money (whatever it proves to be), then don't - but I wouldn't be worried by it.
Personally, I don't use MAPP for various reasons, but cost is not amongst them. (Not owning many combustions is a long way up the list though.)
