How about getting the money, giving some of it to people who don't have nearly as much as you, brightening their christmas/new year, then saving the rest, for something you'll really need and will actually use for more than a few months?
Meh.
Edit: Oh, and not to sound weird, but the way you act about getting so much money, and how if you don't make your mind up, it could "lead to disaster", I find pretty pathetic, in a way. You're getting £350/400 spent on you, you should be happy with whatever you get, tbh. You're not going to die if you don't get exactly what you want.
