This book is currently being sold for £150 by forbidden planet in the uk online. That's about half what one would usually expect to pay for this book in the uk (the standard version is about £60 iirc). Mine just turned up and it's an absolute beauty of a book and certainly a great companion for the deluxe Dressing and Sculpting galaxy books released a few years back. I haven't been able to look through it in detail but I can tell you that there's a lot more to it than the standard edition with plenty of shots and drawings I've never seen; it's still pretty expensive and weighing in at around 12 KG/2 stones you've got to be pretty serious about wanting this book but as the sort of thing you'd be holding onto for decades I doubt you'd feel you'd wasted your money.
