highly recommend pegheadNation. if you look on the opening page there is usually a free 30 day offering on any of the courses. they offer up some world class players who are also excellent teachers-something that's not always the case.
the cost is very reasonable imo also.
youtube is fun and you can find some things quickly, but with a course, you get a graduated program that takes you step by step and leads to a positive direction, rather than wandering around and maybe not heading in the best direction-hope that makes sense.
good luck
