Good Alarm??

Any suggestions on a good alarm for my car? I have a stock alarm and want to upgrade. Viper? Clifford?? The Aladdin 2000 is pretty cool though. It comes with a mini-pager that alrets you if something sets off ur car. Does anyone know of a security systems that has a paging feature on it (but without having to carry some big bulky pager)?? You can check out the Aladdin system at www.gpome.com Any help would be appreciated!

Rotweiller or a Pit-Bull!! That usually does the trick!!!
