What IMU is better for the quadcopter?

I am trying to make a quadcopter; but I am stuck in deciding which IMU should I get and like what features should I look out for? and do I need to programme it in any way??

HobbyKing.com has a contoller for multirotor aircraft that is easy to setup and program and costs $30.18, Product ID 9171000073. I built my own with all the parts needed from HobbyKing

A quick google search found this and many other existing forums discussing the same thing.
