Omega Al-100C add-on alarm

Is this unit any good? Has anyone ever installed this unit in a 2001 Ford Mustang GT, or any vehicle for that matter? If so how hard was it, and does the system work good?. I am not a professional installer but I have installed an Avital alarm in my 1990 Mustang and I am mechanically/electrically/electronically inclined. Also in this sites vehicle wiring info there is no listing for my vehicle. I went forward/backward in year and I believe that the wire colors were the same. I just want to confirm this before starting install. Also has anyone integrated an add-on remote start on this vehicle?  A little from column A, a little from column B.

I haven't used one of those Omega add-ons, but I know that's what LoJack uses for their alarms......I've seen them and they look okay; nothing special. If you're considering an add-on remote start, first make sure your factory remotes will work with the car running.
