Just came across this, and thought some of you might like it.Free Scores for Classical Guitar
Loads of scores (notation and tab)in .pdf (Adobe Acrobat)format, with a midi of each piece too. Variety of styles, mostly classical but quite a lot of modern stuff too.
The guy who runs the site also gives some comments as to the playing difficulty of the tunes.
I really like the site.
Enjoy!
