I've recently been in the market for a top of the line alarm system. It is going into a 1993 Honda Accord. Cost is not a concern, this is one item I am not going to skimp on. I want a fully-covered vehicle, and the peace of mind that comes with it.

So far I've been doing a great deal of research online and have begun talking to alarm shops in my area about different brands etc. Originally I wanted the Autopage RS 1000 OLED (Or C3 RS 900 LED because I've heard problems about the OLED remotes) but the owner of one of the shops I went to recommended the Clifford 50.7x because of their history/reliability. (I've tried emailing AutoPage with no response).

I liked the Autopage because I can use my cell phone to unlock/lock/arm etc. and because of the GPS tracking feature. The man said that DEI also has a GPS system.

I would appreciate any input on high quality alarms out there, and also comparisons between the Autopage C3 RS 1000/900 and Clifford 50.7x with GPS. So far I've only been able to find a somewhat decent review/comparison in 'Performance Auto & Sound' magazine.

I am getting in addition to the brain:
shock sensors Standard
tilt sensors Good option
microphone What?
piezo sirens Work well but need to be delayed if you use a glass mic
two way paging Standard
vibrate remote + sound Standard
starter kill Standard
secondary starter kill You only have one starter. No need to kill it twice
fuel cutoff Good idea
remote unlock Standard
remote trunk popper? If you have a power trunk yes. If you don't have a power trunk then add a 522T
interior fogger? Unless you want the fire department to destry your car then do it
vehicle tracking system C3
proximity sensor/microwave sensor Only on a convertable
back up battery (sirens too) Get a hood lock
one mile+ range Standard
neutral safety switch kill What?
hood pin Standard
rear door handles for front handles, no key hole Cool but you better have a backup if the battery dies
Remote Vehicle Starter? Standard
cellular notification C3
^any additions are welcome.

I like that the Autopage offers an unlimited number of uses through cell phone. I want to be able to check the status of my car from my cell phone often. Feel free to mention other alarms if they're better.

Also, does anyone know if the Clifford/Autopage alarms use a cellular-type signal for the GPS, or a satellite-type signal?

Any help is greatly appreciated, thank you in advance.
