Hey Champ,
I bought a Mongoose M80AM Series. Best for insurance as it has 3 point immbolizeation(spelling). Shock sensor, dual microwave sensor(protects inside and outside of the car) and also has the option of auto window up(flash point brand not mongoose...as mongoose have a tendacies to fail) Very good alarm..I like it. i ended up paying $600 for the alarm system fully installed including a new motor for skyline driver door as it doesn't have a master motor in it only slave.
