Buy the bundle if you can possibly afford it. Not only are you getting six ebooks for a great price (that you set!!!!), but you're also striking a blow against DRM by proving that people pay for quality digital content.
Also, if you've never read The Last Unicorn, it's actually really funny and self-aware. You may have seen the animated movie some years ago, but IMHO, it's even better as a book!
