I just found this site the other day and they have some really good free lessons. Not only guitar, but a ton of other stuff. I thought you guys might enjoy.

Guitar Center has some good lessons too. They are supposed to come out with some new lessons that are quite different. I emailed them last December and asked when the new lessons were coming out and they said maybe January. Well, it's the middle of March and still nothing. Oh well, the free lessons are pretty cool.
