G-CON Light Gun

Now, here's the thing. I bought Time Crisis recently for PSOne. Now, to play it with a normal dual shock controller is a bit tricky but with a light gun it might be a lot better. Trouble is, I don't really want a gun in the house (even a toy), so I don't know what to do. If I bought one, I would have to hide it from everybody. I would feel silly being seen using it. On the other hand, I think on my own I would be "Wow cool! I just blew that cocksucker away!". Now, which is the stronger emotion?
