Ignore the thread title. I edited my post...
Is there really any difference between them? I was looking at the Viper 5900 or the Python 990. They seem the same. All the way down the product line. Even the web sites are similar.
Does anyone recommend one over the other?
I don't really need the remote start or lock function. I just want the thing on my key chain that will beep when the alarm is activated.
Any suggestions?
Also, can extra sirens be added to any system or does the system have to specifically allow for expansion? (I know absolutely nothing about car alarms.)
