I have been toying with the idea of getting a combo light/laser, but am also torn. I can see the benefit of having a blinding light being in the face of the intruder, however you need to know where the intruders eyes are, and if it is one alone, etc.
On the other hand I know that the familiar plants, furniture and corners we know so well in our house may appear to move places when in a high stress level situation.
I am more in line of thought of using the gun to clear my way into securing wife and kids in a safe place, (most likely my bedroom) and calling the cops.
I like tex n cal's idea of a mini crossbow to avoid waking up the neighbors
