Yep, the good news is that all levels are free here. it takes time to progress and I guess we picked one of the most demanding instrument.
Nevertheless, don't use your credit card there is plenty of stuff free on the net, not only here and I'm talking about legal freebies. You can listen to last.fm, they have a classical guitar channel. Pandora also is interesting: set you up with say a 'segovia' channel and you'll listen to a bunch of public domain material... Get to know an author like Bach, Giuliani, Sor, Tarrega and work on their pieces from simple to most complex. Pretty rewarding after some time: you'll become familiar with their style, cliches, etc. and playing their music will become easier (duh, well, except Bach maybe).
