Most of the information in the book (eg all the art sources, which are obviously a bit of an obsession of mine!) is also available at
http://78friends.com and also the book is available at an eBook through Amazon/Kindle - although unfortunately I think that's just in the US. We certainly can't buy Kindle books here in AU
I don't think you probably *need* the book - although the gold edges on the Kunati edition are very pretty. I use the LE to read for myself but I love to show off the Kunati one - people really like to look at the detail in the much bigger cards. Perhaps you can pick it up in a trade, or buy it at a discount from Amazon US?
