I prefer my classical-piano sheet music to be professionally edited, published, and printed. I like the help with fingering editors provide, and I like big easy-to-read pages in front of me.
When I am experimenting with new (to me) composers, though, I like to experiment without making a monetary investment. (I will certainly make the *time* investment, practicing.)
Free-scores.com is a superb resource for students and instructors (and for the people who help support them). Scores and sheet music not subject to copyright are made available to music-players everywhere.
