I have the 2gen 2-way Viper 779 security system with alarm.
It's my this is my 4th auto with a Viper remote start in the last 12 years or so, not one issue.
The dealer even replace a control module, under warrenty after a really bad wreck, for free.
Although I believe the repair shop fried it and it's didn't go bad.
Believe it or not but you can get the upper end system installed at Best Buy, and take advantage of there financing offers.
That's what I did with the wife's Ranger Edge, plus installed teh head unit and XM, I still installed the speakers. lol
I'd go with the Viper 5701 Responder.
Not sure how the SmartStart system works, but sounds pretty cool.
