So Confused

So I've been working at this really nice and well known center as a sub, it's nice and I really like it but the hours aren't set. I don't like that one week you could work every day and the next week you might only work one day. So I got a call from another center that I applied at and they want me to work a set 20 hours a week as a lead preschool teacher. It also pays $.50 more. The problem is that it's at an unknown center so I'm not sure what to do. I really need the money but it will look better in the long run if I stay at this well known center. I talked to everyone and Dan freaked out and said that I should stay at the center where I know I'm going to be making money but I don't know. I took the job at the less known center and now I'm not sure if I made the right choice. What do other people think?
