The way i look at it if the damn thing functions like you want it you dont have to go with one of those high dollar alarms... 300 bucks is way to much for me to pay for an alarm but thats just me a cheap as. I got an aolin from ebay for 99 bucks and it has a built in pager which is what every alarm really needs, yeah the lights and siren are good but how many times have you sat at home hearing a car alarm go off and not even looked out the window...thats how people are gonna do your bike alarm going off and they arent even gonna look out the widow, but if you get a pager feature it will tell you your getting jacked and let you decide what your gonna do. Only thing that woudl justify pay 300 bucks is if the damn thing had a built in tracker and called the cops. but hell with a 1200 meter range and engine disable feature ( if i can find my ignition wires) im happy with what i got
