Our store does a dollar, which I think is pretty fair if you plan to move to a TL position eventually. I would ask for more, and negotiate down to a dollar, and be prepared to explain why you deserve more money.
I don't think going for GSA is good if you're going to be in that position for more than a year. I consider it more of a transition/beginner role that people shouldn't be in for too long. So in other words, aim for TL, and look as GSA as like an extended training.
