what is the best alarm money can buy?

Right now, what is the best alarm money can buy? What are the top models out there? i want a new alarm to replace my  viper hf600.

viper 791xv (clifford matrix rs 3.5).  basically pick one that has features you like/need and add all that you can to it to make it unique and truely yours.  do an awsome install with origional ideas/techniques.  good brain location, hide the starter kill...  smart routing of wires, loom, backup battery.... piezo sirens strobe lights timer relays and the list goes on.MECP certified installer

Can you add the vis anti-hijack switch to this alarm. this would be very important to me to prevent loss form a car-jacking!

I am new at this alarm stuff, but I would have to say everything that I have seen and heard, stick with DEI all the way. I really like the Clifford ones the best, I like the way the remotes look with the CF finish, and I like the siren more so then the one that comes with the viper. Clifford RSX 3.5 or Viper 791XV, all comes down to price and preference. And like sroth said, add all that you can to make it yours. I like the fact that I can roll my widows up and down, start it from in the house, honk the horn on demand, I like the fact that when it does go off, my air horn activates. Now if I could just make it do a burnout from the remoteWill              Just my $00.02

BTW I am not a professional(well at procrastination maybe)

Be Gentle, I'm new to this :-)

So what's the difference between the RS 3.5 and the Avantguard 5? Clifford's website makes it sound like the Avantguard is better, but it doesn't have the 2-way support. Could someone clue me in? :)
