heres the deal, if you get an alarm, mith all the sensors in the world, how are they going to get in your car, without setting them off? dont worry about dfs. now, theres a lot of good companies out there. viper and clifford are the two best in my opinion. in fact dei, known as directed electronics, in which viper is a subsidy of, just bought out clifford. these companies offer everything you could want. they also have some sweet install guides so you can install them yourself. many of the alarms come with the glass sensor (which is basically a microphone and should be mounted an equal distance from all windows, almost all with dual stage shock ensors (which only means that it can distinguish from wind hitting the car and a person doing the same) the pins are accesories which can be bought cheap from them directly, as well as the battery. what do you mean by an intrusion sensor? also, do you want a backup alarm or did i misread? personally, viper and clifford's quality is legendary so i would go with them. any decent shop should carry them as well so you can always get is serviced or whatever.
