About anything DEI is a good alarm system. Viper, Hornet, Python, Clifford, Avital. All these are by Directed Electronics Inc. and make a decent system. All will have the chirp for audible confirmation, plus the flashing the park lights for visual. Most have the option for keyless entry. I installed a Hornet over the weekend and it went just as easy as my Viper I have. I think you get a better warranty with Viper, but they seem to all be good.
