Really, I agree with Elmo's shotgun suggestion. You can learn to use a shotgun easily, it requires very little ammunition, and used shotguns can be had at very reasonable prices. When you say "I don't want to own a gun at this point in my life" that sounds as if you're simply placing guns off limits for reasons you really can't explain. Your choice, but if you really are concerned about defending your home, defend it. Don't half-ass it.
I agree that a shotgun is a good idea. One day when I have a more permanent home of my own, I'll buy one. But right now it's just too much of a hassle. I don't have much money to spare. I don't have much time to spare on learning how to use it. My living situation is far from permanent and it's likely I'll be moving to a different state in the next year or two and having a gun would just be another hassle while I'm moving. And most importantly, I live in a safe neighborhood and I'm really not concerned about people breaking in and trying to hurt me. If I was, I'd go with the shotgun.
