I am a big Risco fan but I believe most on here don't like Risco.
Their bells are rock solid and only had 1 XS3D faulty in 6 years.
Low end panels such as 480 and CPX are good for the money with built in speech dialler.
600 panel is solid .
Their new B Ware detectors are easy to wire, set up and install.
The Lightsys and Agility 3 are very good panels plus I would say the wireless is the best out there.
Remember you can connect cameras to the Lightsys and agility adding extra security.
I'm waiting for the Risco bashers now....
