I actually just bought this this weekend. I saw it marked down to $50 at Wal Mart and couldn't pass it up. As someone said previously, the box sold it for me, all those accessories, good stuff.
The castle looks great in red and black, I don't like the giant swords and the fact that the third and fourth floors don't have ladders, but over all it is a very nicely designed castle, especially for this day and age.
In reality I bought this set for parts. I bought this set for the chains, I bought this set for all the weapons (minus the KK2 swords), I bought this set for the flags, lances, window pieces, special black and red harry potter style door, the wood staircases, for the dark grey saddle and the old school blue horse mask. It's a great parts set even if you dislike the castle itself (which is actually quite good).
Also, I think that the new falcon shield actually looks good with some falcons, and the blue and white sheilds are nice for BFs too. I do like the Scorpion shields, but I could care less for the other jelly bean crap, it looks like something toddlers would play with.
