Guitar players - suggestion box

I'm a hack player without any extensive training or a healthy practice regimine. However, I'm always looking for something interesting and challenging to play however far and few between I may come across something that appeals to me. For a while now I've been messing with Chet Atkin's Vincent which is a cool and somewhat challenging tune that is tabbed out very clearly and easy to follow.

What tabs have you found online that are really well done plus fun and/or challenging to play?

Oh and another is Moonlight Sonata. Some tough shit in parts of this one for me at least.
