I use a plastic gastronorm with a lid (e.g. https://www.nisbets.co.uk/kitchenware-and-knives/food-storage/plastic-gastronorms/_/a33-3)

£60 for a 5kg IIRC - it pains me to even post that tbh!
In an effort to reduce mess, I divide and roll my dough balls and then wrap them individually in clingfilm and just chuck em together in a baking tray. Easier to transport that way, and easier to bung unused ones in the fridge too. Clingfilm is shitty tho - instant waste plastic :(
Propane patio gas from Homebase. Not sure it's the most economic/cheapest but it was available and I needed it that day. You'll definitely save cash by ordering one online if you can wait.
For gas it says to leave door open and keep the lid on the chimney. I've been doing chimney open and door on and off. I hadn't actually realised I was supposed to keep the chimney cap on, whoops. Having the door and the chimney cap on will extinguish the fire as well, obviously.
Edit: that canister is the exact one I have. But if you google patio gas you might find something cheaper.
