i started off learning by myself too...i reckon its better to get to know someone more experienced and jam together...instead of paying and going for classes... i feel most proficient guitarists learn on thier own...but mind you thats not why i did this by myself... u have your own time and you dont have to travel around...sometimes when you're busy and u can't attend class... then again i guess it boils down to personal preference really.. i feel really comfortable playing at home everyday... i pick up some songs i really like and try to learn playing them... and them its awesome sites like this one i have gained more knowledge.... and i'm still learning... i'm still far behind and there's a lot to learn..

just my two cents mate...
