Good point. Here's a part listing: http://www.bricklink.com/catalogItemInv.asp?S=10231-1 http://www.bricklink.com/catalogItemInv.asp?S=10231-1 At first glance, looks like the only unique parts are the sticker set (~$5-$17) and the minifigs ($3-5). How many other parts you need to buy would depend on the size and variety of your collection.
