I also just bought lifetime member on SBL, so, I don't have to worry about ever paying again over on SBL. I'm actually leaving in about an hour to go pickup my first bass from GuitarCenter.
I'm hoping GT and SBL will compliment each other, if I can come up with some logical schedule of practice between the two. Hopefully studying/practicing both bass and regular guitars don't become conflicts and make my brain explode.
