I saw a real cheap deal of a motorcycle alarm at JC Whitney. It seems to have almost all the bells and whistles needed to make it worth checking out for only $60. Here is the link.

 

i have (and bought my g/f) a Gorilla alarm. i believe most sites have them for around $95 SHIPPED. although it wont taze the culpret, nor will it immediately send SWAT after your bike....for $95 it does its purpose and makes a **** load of noise. it has 2 settings.....1) just regular alarm, 2) sensitive (wind will set it off, lol). i see no need for a fancy pants $400 alarm, but to each their own. if you want a cheap but functional alarm, search up Gorilla Alarms.

 

This says it has 8 different settings of sensitivity, panic button, engine shut off if hot wired, and a panic button, plus a few others.
