Bound to Happen

The GF bought a house in Flint, near Kettering University about a month ago. Property in Flint is pretty damn cheep and she's fixing it up to rent to students because there's a serious shortage of housing on campus. But the inevitable happened last night, someone broke in and stole a bunch of crap. Mostly tools but some other stuff too, they left the work lights and shopvac but took the $2 wax rings for the crappers. They got in through a window in front of the house, our thoughts is that it was someone who lives in the neighborhood, maybe even the PWT slimeball that lives next door (4 cars, 2 of them run and he routinely scrapes the orange tow sticker from the one on the street.) So I'm thinking that once all the construction is done in the house that I go through and do a security upgrade, nothing seriously expensive, good locks on the doors and windows, a deadbolt plate on all the doors, motion sensors for lights above the front and rear door and an ADT sign. Also going to try and find someplace that sells security laminate for the windows, a'la It takes a Thief. So far, the only place to buy the stuff off the net that I have been able to find doesn't sell it in the thickness necessary to stop a smash and grab. Any ideas that might actually work would be appreciated.
