Remote Starter Viper vs Compustar

Hi! Went to a Viper dealer that had recently stopped selling Viper products. Called another and the same. I need to find something for my Tahoe, reliable 2 way. Anyone got any experience with Compustar products?

You might want to check over on www.the12volt.com forum. That sight helped me out a lot with the wiring of my DEI remote start.
