When I was a kid and was still living in Poland, my parents used to have these few kilo rechargeable gas bottles and compatible stove, which we used during holidays. The nice thing about this was that the gas containers could be refilled in LPG equipped petrol stations for the same price as the gas used in LPG converted cars (so a tiny fraction of the cost of the backpacking gas containers popular today). Is it possible to buy these kind of stoves in the UK?
