Before I took formal lessons on the guitar, I went to several libraries and borrowed videos for beginners. There are also several produced by various performers available from their wesites. I suggest Hap Traum for his teaching videos, CDs and books. There is no best unless you decide what you want to play and how. By that I mean, the style; genre and type of guitar etc. I personally think learning the classical guitar prepares you the best but that is MHO. Luck to you.
