With the mark up that's habitual in the UK and the minimal weight with regards to postage I doubt they would be cheaper from any UK source, if anyone had them. I got mine, first the steel with a wind shield and then a Ti with adapters to take a Evernew Ti burner direct from the chap who's a pleasure to deal with. They both arrived quickly and weren't stopped by the PO to be examined and have charges slapped on them, but that may have been luck!
i love mine to bits, shame Trangia copied it, that must have hit his sales.
