A:Answer The Compustar 4900S kit is a fantastic value when it's on sale for less than $300 (it will be, regularly), Compustar CS920-S kit is cheapest when it's on sale (remotes are pretty cheap but get the job done), Compustar RS1B-AL is a higher end control unit from Compustar but only comes with one remote and shouldn't really be considered over the first two unless you have a manual transmission or if this is cheaper, and Viper DS4VB is a great option as well with built-in bluetooth for short range control from your phone. All of these are great options that are reliable and whose remotes can always be upgraded down the line if you ever need longer range.
