The only other option is to modify the once use 1LB Coleman ones, it can be done safely if you're sensible.
Basically, they have a one way valve in them, that prevents refilling and has to be removed.
To me, it's worth the effort as straight LPG is a far better fuel than the 70/30 butane mix cans.

£37 for 4 on the flame King website for US customers but they dont deliver to the UK ... £50 for 1 on Amazon or £28 on ebay looks to be the best prices. someone should import a job lot and flog them here as there doeesnt seem to anything similar really

I just bought some Mr Heater Fuel kegs off eBay from the US, they're designed to be refilled with propane and work well with the Mr Heater Buddy heater

Risking your life for a 7 quid can of gas. Unbelievably stupid. Natural selection doing its thing.
Don't be stupid enough to do this.

Update; Im still using my refills and still alive with no problems.
I have just refilled 6 of the coleman c500 cans, but had a bit of an issue.
I set everything up and tried to refill but I couldn't get much gas to transfer so thought I'd speed it up and put the empty and part filled cans into the freezer.
I put them all in a carrier bag so I could easily drop into the chest freezer. A cup of tea later and I then went to refill them. I may have left them in too long.
Now the cans are well chilled and the gas flows with no problem. I'd pick them up and give a shake and when they seemed quite full I'd disconnect and weigh them.
Now, a normal full can is 620g, and I checked these new refills and they are 650-700g.
They seem ok so I just left the carrier bags in the kitchen.
Later that evening I heard a pop, and later another.
On investigation I found a few of the concave bases has distorted a bit, and one had really pushed out, but thankfully not blown.
I thought I'd best try and burn off some excess gas to relieve the pressure but it wasn't having any effect. I then found the little gizmo that allows transfer of part filled cans and used that to bleed off pressure.
Holding it with some grips is easy enough, but you need to turn the can on its side while pressing the gizmo into the can to release pressure. It comes out as a massive burst of gas, really stinks, and obviously do outdoors and let the gas blow away on the wind.
I quickly got the can weight down to sub 650 so this was ok.
It shows the need to keep checking the weight to prevent overfilling.

I have used about half a dozen of the gas cans i refilled and I'm still alive with no issues.
I have just refilled them all. All filled easily, but one wouldn't fill more than halfway, so put it in the freezer for half an hour and then it filled up.
I can understand people being worried about the pressure, but the thin plastic tube that connects the large donor propane tank to the small coleman cans isn't splitting or bulging so thats good enough.

Hi, Coleman C500 canisters are steel not aluminium.
They rust in the top.
Plus test with a magnet, it sticks anywhere on em.

This is it, just shake/ warm the can, take off any wetsuit and you can empty it.

Why would anyone even consider disposing of a 25 % full gas cartridge ? You just use it until it's almost empty and then just place the canister in a bowl of hot water or use a USB heater to use the remaining gas. I'm truly flummoxed 🤔

Each to their own... But it honestly only takes a matter of minutes, and allows you to reclaim the 25% of gas in each can that would otherwise be thrown away.

I personally cant see the point of getting the dregs out of a almost empty gas canister. Much easier just to buy a fresh new one for how little they cost.
