Well they still seem to be available, although they don't contain much Gas, and once connected you have to use them up, as they don't have a valve, as they use the pierce system, handy for a lamp maybe.
I once saw someone attempt to fit a new one in their lamp - without unscrewing the top of the lamp first. The cartridge shot a good 30 yards then sat there discharging the remainder of its gas! Good job it didn't land near a naked flame.
So if you're going to use them follow the appliance instructions carefully.
I had a kid on a DoE award expedition have one go once when the stove was alight. The rubber washer on the stove had cracked. It turned into a horrible fireball. Luckily we were able to kick the hing out of the way of any harm. They were banned soon after that happened about 10 years ago now for the DoE award. The other problem was with leaky valves on the stoves. It was common for the gas to leak inside a rucksack & saturate the clothes etc. The stoves were quite unstable too as they were tall & could topple over if not on firm ground. We used to hold them down with tent pegs. The screw on cartridges are much safer.

you could buy plastic feet which made the stove very stable and the biggest problem was the piercing pin didnt retract when you removed the old canister a bit od WD40 and it was fine.I still use the 400 series for my lamps (or 2x 206's) i have about 8 left and 5 of the 106? versions for my ACE stove ,ofcourse its far harder cutting a 206 in half to make a 106 than it is t double up a 206 to make a 400
never had a problem with leaking other than not done up taps and one stove i have still has gas in it after 20 years i shook it yesterday
if your stockpiling canisters spray the base and seam with paint or laquer (i use chrome laquer) the rust just loves the seam ,i have about 50 in the bottom shed all still pristine for over a decade
Don't tell the fire brigade. We did use those plastic feet, the holes in them were where the pegs went. Still glad we got shot of them all after seeing one go up.

So long as it it full of gas it should be OK. I t is when they have been sitting around empty you have to worry as they corrode internally.
I know this is a very old post, but I wanted to reply, in case I'm missing something important...
Just bit of background - I found the thread when searching for info/prices etc about C206 canisters, as I have a lamp which uses them. I also have a couple of burners and another lamp which use CV470 cartridges, and basically I'm trying to decide whether to buy more C206s for the lamp, or a 2nd lamp which uses CV470s. Only having to cope with one type of canister is not particularly important to me - the use cases are different.
So back to the "what am I missing?" - surely once a canister is empty, it is empty, i.e. it is no longer a gas canister, it's just an empty mild steel can.
So WOE would you need to worry about whether it corroded inside?
Perhaps vti2007 (who hasn't posted for nearly six years) thought the discussion was about refillable cylinders, though these would be thoroughly checked at the filling plant?
