I've been in love with flamenco style guitar for some time now, but have only found a few, short lessons that are usually interrupted half-way through the first lesson - asking you to pay $.

Now, I'm not such a cheap ass that I wouldn't pay for a high quality lesson, but it's impossible for me to know what is and is not "worth it".

Can someone point me to some free flamenco lessons that provide proper insight on theory?

Also, I don't know that I'll ever be willing to grow my finger nails out to finger pick. Is my best bet to use those fingertip pics (I've never made it past the awkward phase with them)?
