Looked at those and could only find 2 UK suppliers who would send them here (dangerous goods carrier needed) and the cost would be around 175 for a 2kg auto. We then have the problem that the gas not available here for annual service or recharge so postage back to UK around 40 each way.

There is alos anothe "new" gas, FE200 but that's also not available here.
