Maybe too hard still, but try Using the Word, that main melody. It's not that hard, and it works your fingers a little. There's an ok tab on mysongbook.com if you use GP.
It is actually very useful for composing when you don't have an instrument handy and for saving the timings for otherwise hard-to-decipher tabs. It does help a lot, but $50 is a bit much, I must say.
