I'm still trying to make up my mind about which version of "Aladdin" to buy this week. With all the sales, I can get the 2-disc set at a number of b&m's for around $15 and change. However, the box set also interests me, but only for the enclosed book. If anyone has the box set, is the set worth the extra $20 or so just for the book? Or can I learn just as much about the making of the film via the DVD's extras?
