WTB Youth Guitar

I posted this in the classifieds but thought it might get more exposure here. My 7 year old son is wanting to take guitar lessons. We went to Guitar Center for a free lesson this past Saturday. He really enjoyed it and is going back this Saturday. They let him use one of the the youth small guitars there. He is wanting an acoustic guitar. Does anybody have a 3/4 size acoustic guitar they are interested in selling?



Also, do you have any advice for a young one interested in getting started?
