I would do the full access at 15 bucks a month, it is a lot cheaper than 40 bucks an hour for lessons. You could do the beginner stuff in a month and cancel if money is an issue. You will get hours of lessons for 15 bucks. The free beginner stuff isn't much help believe me I have searched the net and there isn't much stuff for free that will get you started. I too am familiar with a keyboard, and the fact there is no c or f string was a bit strange,but there is c and f "notes" in many places on a fret board it is an easy transition from a keyboard with the proper explications. If you can play a piano you can play a guitar..

run-on sentences are fun

Yes I prefer them myself
