It's available slightly cheaper (about a quid) from World of Magic. I'm not sure if that would actually be cheaper after postage.
If the book's purely for interest, maybe give it a while before you buy it. £900 is a lot of money to spend, and I'm sure you'll want to dedicate enough time to the business to justify that big outlay.
