I think there is a trememdous value in sitting with someone in person but I think it enhances what you learn on your own. And I'm not sure if it has to be an instructor-instructor. You know, just making time once a week to go over a guitar playing buddies house and playing for an hour or two can be beneficial.
I would say that shop for instructors until you find one that is a little more reasonable in the price department. That's what I'm doing and continue to work on your own.
Good luck. BTW, I didn't even start playing until I was 45! Oy. I figure I am going to be the best guitarist in the retirement village when I finally master this thing. :cool:
