You really cant go wrong. Most of the bid companies (viper, clifford, compustar, and others) are owned by DEI. I would personally take compustar just because their remotes seem to last longer and can take more abouse. Also i see no point in spending so much on a two-way. All it does is inform you that your shit has been jacked. A nice without going overboard is all a person needs.
I have to disagree with that. The new 2 way alarms have the paging capability buit into the remotes. If you had seen or installed the old school pager systems you would know it was a pain in the ass. You had to carry a separate (bigger than pager) unit with you. Theres nothing worse than your alarm going off and you don't know. With the 2 way system you know it's going off because your remote notifies you. Plus you know if your doors are locked and if your car is remote started without having your car in view. by looking at your remote.
