You can get them in the U K for +- 150 quid.A chap on here had one said it did not get hot enough google camping water boiler. 
So could of saved myself £50 if I shopped around? 
Never mind-Corwoods seem to have a good reputation, perhaps if it goes wrong they'll be better to deal with. 
I don't mind either way. 
It's a good buy. 
Can't believe someone said it doesn't get hot enough. I started yesterday, one of the first jobs was a full 100m reel out. After a few minutes working there was steam coming off the brush. Went back to turn it down, it was only on just over a quarter!
Darren,Do you a big difference now with hot water?
I've had hot for about 3 years now bud. 
Just changed the boiler is all. 
But yes-there is a world of difference between hot & cold. 
No-one with any sense whatsoever would say otherwise. 
On a side note, I'm 3 days into this bottle but I have a hunch that this boiler is using less gas than the old one. 
I'm gonna measure how many litres 1 13kg propane will heat to a good working temperature.
