I have to dissagree, Coleman's are ok, but the generator can be temperamental unless you use the Coleman fuel exclusively.
I vividly recall one, possibly a Sportster model, arcing through the air into Harefield after the genny had failed for the fourth (?) time in two or three months.
The main thing with all these stoves is to opperate whichever you buy with one of those folding windbreaks wrapped as close as possible around your kettle / pan. They really do make a huge difference to the boiling time.
Good luck with whichever stove you choose.
