steering wheel lock: how hard is it to break?

[little x]

How hard is it for a theif to break a steering wheel lock?

I have a push button starter/switch ignition right now. And the only thing that keeps someone from just starting it up and driving away is the steering wheel lock. So how hard are these thigs for a theif to break? I'm thinking of installing a hidden safty switch so that the truck won't start when it's flipped.
