What should Erick Aybar get in a contract extension?

If recent reports are to be believed, it is only a matter of time before the Angels lock up Erick Aybar to a lucrative contract extension.  Nothing is official yet, but reports are circling around a contract somewhere in the neighborhood of five years and $50 million for Aybar.  That seems to be what Aybar is asking for, anyway.  But is that what he should get?
