Certain suppliers can take much longer to deliver than others so you might have to stick to the kettle for a little while yet. As for the fuel. You could use normal purple mineralised meths from any hardware shop. Problem there is that the vapours stink the place out and it is recommended that it should only be for teacher use only, and not general class use. We use IMS (industrial meths) which is basically the same stuff without the nasty dye in it, only problem is that you need a licence to buy/keep it. This isn't hard to obtain, but is yet another hurdle.
