You might get lucky at your local tip if you ask the people there nicely - although there seem to be more calor than gaz bottles so I use calor now. Which is also cheaper.
I got mine off ebay for £6 and it was local to me, had to wait awhile till one come up but wasn't in a great rush. Just need to exchange it now for a full one
