That's pretty close. Mine was about $300 when I bought it, although price has come down. Keep in mind, too, that with pre-wiring and the PATS Bypass you're looking at another $65 bucks or so.
Honestly, though, if I were to re-do mine (which I probably will after graduation), I'd go with the Viper system. Mainly because of the SmartStart App. It basically gives you unlimited range. While I won't need it since I won't be across campus from my truck anymore, it would be a nice thing to have. It would run about $400 all together, which is not bad considering low-end models cost that to be professionally installed.
If you're going for budget + performance (which I was), Code Alarm seems to have the best options.
