Slasher hit it right on, the site can be overwhelming with its vast amount of content. But it does represent an extremely good value for the fee, no question about it. Only reason i stopped full access (temporarily) is due to bandwidth issues. But more than just the lessons, what attracted me to the site was the community. I lurked for a while before signing up and found the members here to be more mature than some of the boards out there. Some of the "free" sites can be a little hostile and unstructured with unmoderated forums. This site is professionally run and the members as well as the instructors are always willing to help and provide encouragement and feedback.
If you decide to opt out after a while permanently or temporarily, theres no questions asked and no hassle chasing your credit card billings.
Just a very well run site. :)
