I agree with JJ90. GT is so cheap compared to a private teacher that it's almost free. AND every now and then, they make special, rediculously cheap offers, like the "one year + GigMate toolkit + 5 CDs of lessons and Backing Tracks worth roughly 400$ for 99$" that they had when I signed up for a full membership here. That's not expensive at all, really. Especially not when you consider the quality of the lessons here. And the highly helpful forum is only a plus.
