Sometimes on ebay you can find a coleman hose that attaches the stove to a big propane cylinder the adaptors are available but it is recommended that the coleman small cylinders are not refilled (and I know that they now cost singly what you used to pay for a twinpack!) I am just using my last couple of small cylinders but will probably try a bulk (3.9?)tank when they run out.
I had been looking at refilling these too but decideded on a coleman hose from the USA. Tried it last week and it worked a treat. Have been told that the seals can fail on refilling the disposable bottles.
