eBay with a$avings has the Skylink SC-100 Wireless Home Security System Deluxe Kit for $79 with free shipping. Features 110dB siren, rolling code technology, and includes control panel, motion sensor, 2 door/window contact sensors, keychain transmitter, AC adapter, batteries and mounting hardware.
I bought this unit several years ago, but the package that I bought also had the wireless autodialer included. Additionally I bought a water sensor with the unit so I could tell if the basement was flooding without going down there each rain storm. Everything works great. The batteries in the remote transmitters work for about 2 years. I don't use the IR sensor because of the cats... and in the middle of the night a false alarm can be unnerving.
[edit: I note that the 'wireless auto dialer I mentioned above has wireless communication between the alarm system and the dialer. The dialer itself does not communicate over cell phone service]
skylink? Sarah Conner?
I believe it's Skynet and Sarah Connor.
