Should I stay or should I go now?

My violin teacher is planning on moving to the other side of the country within the year. I've been with her since I started learning for some 16 months now. I'm not sure if I should stay with her until she leaves or go to another instructor right away. I'm thinking that building a strong relationship with your teacher is pretty important; so if she's going to be leaving, it may be an opportune time to start again with somebody new. I've already gotten a few business cards from other instructors in the area. Hmm... I'll have to think about it some more.
