I second this guy, Daniel if i remember correctly. Awesome bloke, excellent service and the poor bloke works his arse off. Came to my house at 7pm or something and didn't get away till around 11pm all cause he couldn't fit me in through the week
I went the m80 and would also recommend this, as others have. Top alarm, has all the gizmo's that make it insurance friendly and also complies with NSW noise pollution laws. I'm not sure if this is something all alarms do or just few but It's nice to know your alarm adheres to state law
