I just had my 98 chevy broken into and stole my Kenwood radio. I want to buy an alarm now for it and I don't know what brand to choose. I saw previous posts and the hands down winner is the Viper line or just about anything from Directed Electronics. Which I am seriously considering the Viper. I have found some good deals on ebay. I had a co-worker try to sell me on the K-9 brand of car alarms. I never heard of it. I know what features I want, I am having a hard time deciding what brand to choose. Before I buy something I like to do my research so I make sure it will meet my expectations. So whats your advice?
