I'm new around here but have owned a locksmith business for the past 15 years and figured I would chime in.
I've followed up and repaired hundreds of homes and businesses that have been broken into and have NEVER seen or heard of a common criminal picking a lock to get in. Sure there have been some locksmiths that turned bad or people that knew how to pick a lock that went after something specific, but it is not the normal.
Smash and grab is what it's all about. Bust a window, kick in a door, peel off a roof vent or gable vent or just drive a car through a garage door. Speed is the key. You want to deter them enough to make them look around at your neighbors houses and see of any of them look easier than yours.
Medeco makes good stuff but we do not sell it. We are a Primus dealer and a GMS RX dealer and sell a lot of both, but usually it's more for key control than anything.
Grout filled, commercial grade, steel frames are awesome when they are installed properly. Team that up with typical commercial hinges (pins can not be removed without opening the door and removing a set screw first) add locking hinge pins, decent deadbolt, door reinforcer and a mag plate and nobody is going to waste their time with that door.
Clear out any shrubs, bushes or anything from around the building that would give anyone a place to hide. Add large flood lights with steel cages to keep someone from busting the bulbs. Add a ADT sign or some sort of security system sign or decal to the door or yard (just the sign works well, crooks don't want to set off an alarm so they will go to your neighbors house).
If you're uber paranoid, then you can add a camera system with GOOD IR cameras that record to a DVR or server and allow you to view on the internet with your phone or laptop. Also a security system (door sensors and motion sensors) that uses a cell phone service and you're more secure than most commercial buildings in your city.
In reality, a solid frame and door with a deadbolt will deter most smash and grab folks and that is more than a lot of commercial buildings use. Just don't forget to insure whatever you have sitting inside that fortress that you have built.
