well, i got my clifford alarm from ebay before (same thing as Viper anyways, both from DEI), if its a powerseller that either ADMITS the thing is refurbished or something, then i think its good...but theres no real warranty, so do your research.has anyone got a 2 way viper alarm from ebay before? i kno that some products from ebay isnt good so im not sure. only reason is cuz in best buy it cost $300 and on ebay its about $190 so thats a huge difference.
let me know cuz my teg needs a alarm system
ima have to disagree because of personal experience. i got the Clifford Matrix 12.5X for around $120 and got installed with the starter kill, 2 way alarm, 5 aux inputs etc.Stay away from ebay for DEI alarms.
