Alarming decision!!!

[marz92]

Looking for some advice, I wish to replace my alarm system and immobiliser. Had thought about going down the Clifford route using their 650 system which is Thatcham 1. Cost wise is £420 fitted by Sextons of Swindon. All singing all dancing kit. I believe it is not microwaveable. But does have good features. Should this be something I am looking for? Or is it better to go down the route and use this guy from Petersfield who fits Meta alarms. The same as what the TVR factory fit. Anybody got some good advise. People on Pistonheads do speak highly of Clifford Alarms but then again alot swear by this other guy from Petersfield who knows all TVR models inside out using Meta alarms. Your call please!
