So you want a noise maker that no one even looks twice at anyway?
The only good thing about aftermarket alarms is if you buy a 2-way pager system or one that is connected to the internet and then to your phone (Viper now offers this)... in which case it's $500+ for the alarm + install, plus $150+ for the internet connectivity pack for a year a think.
One that isn't somehow able to contact you is just another noise maker and at that point you're better off with an OEM alarm unit.
