I first learned (still learning actually) from Gary Primich's audio lessons. While the first tape I bought to learn from was David Harp's stuff (while the information was good, listening to David Harp was excrutiatingly painfull...I felt like I was in a class and Barney was the teacher) Gary Primich's approach to teaching was, how shall I say it, more...mature. There is no booklet with his tapes, but it's not needed. It's 2 tapes, 2 or 3 hours long for about $20 and well worth the price.
