Tony's Acoustic Challenge in my opinion, is the best I've found! I've been using his program for a week and have seen exciting improvement in my guitar playing already. My daughter is learning too and she has learning disabilities. I find his instruction is easy to understand and keeps the motivation level high since we are actually learning to play something besides notes and chords and theory. We took 2 adult education classes and ended up frustrated and put the guitar away for several years. I tried Youtube videos and 2 other DVD courses, none of which taught how to play in simple straight forward instruction. If you really want to learn guitar, I highly recommend Tony's Acoustic Challenge!
