I don't have extra money to waste, and I've replaced locks and latches in a couple cars. Its a PITA, and doesn't have any real return value. The Tuffy box wasn't that expensive, and its a good value. I can leave my garage door opener, registration, leatherman, and assorted stuff in there without worrying about them.
The chances are that somebody breaking into your jeep will just grab what they can and take off. They're not going to spend 15 minutes banging on a metal box while you call the cops, make a cup of coffee, and wait for them to be arrested.
Go Tuffy. Way better, way more secure.
