At a DEI dealer. DEI 520T. It comes with a trickle charger also, a MUST for any alarm. Sometimes eBay has them too.

Google search for "DEI 520T"
There are alot of online retailers that sell them for around $30-40. While you are at it, you may also want to get a siren (DEI 515R) with a built-in battery backup.

Here is a good thread offering advice on alarms and car security in general...

I heard the backup battery siren is only for the Avantguard systems. Anyways, the backup battery, when hidden, should suffice. Your siren(s) should also be hidden with no visible wires. I recommend at least one external and one internal siren, you can even wire up your horn with the alarm.

Actually, the DEI 515R battery backup siren can work with any alarm system. I have one in my Python system. You wire it up just like any regular siren except that you have to run a +12V and ground which keeps the internal battery charged.
They are not that expensive ($30) and can add an additional layer of security on top of a battery backup for the alarm brain.
