From a $$$ and self defense perspective a shotgun is the way to go. My advice for you and your wife while at home....have a plan. Know what you're going to do before you do it. Think of different scenarios and how to deal with them (she grabs the phone and calls police, you get the shotgun and train it on your locked bedroom door, while waiting for the boogy man to make a move).
Although a shotgun is great tool, not many people want to walk around the house with one all day. I'd get a shotgun first, then take a look at a good carry gun (something you can carry around the house). I say this because sometimes you wont have the luxury of an advanced warning. If you want security, it's best to be prepared.
Also, if you don't have a CC license, get some good pepper spray for you and the wife...recommend Fox.
