Does anyone have suggestions regarding car alarms on the S2000? I've basically decided to go ahead with the Honda alarm ($273.60 on handa-accessories.com), but I'd like to know what others who already own this alarm think of it, as well as what owners of other brands have to say. Is there any reason I should spend the money on a third-party alarm rather than sticking with Honda's?

I'm also thinking about putting in a kill-switch, but a friend of mine suggested that they aren't really all that useful. From what I understand, they can be dirt-cheap to purchase and install, and can reduce insurance rates by a small percentage (I think it was about $10-20 off of my payments, which is pretty decent). Has anyone else installed any other forms of theft-protection on their car? Any suggestions would be greatly appreciated.
