I've been using an alarm by Crime Guard, their model 350i but sadly its been discontinued---good thing I bought several and kept them waiting to be installed.
These by Code Alarm seem to be close in features and program ability, not a lot of stuff you might never use:

These "low end" type systems tend to be very easy to install. Once the "brain" is placed securely the only real wiring is connecting the trigger to the dome light, finding an always on power source, tap into an ignition on hot source (ie; radio) mount/wire the siren, tap into the parking lights circuit, test, arm and you're good to go.
Here's the wiring manual, last two pages:
