I have one for sale
I've had Clifford,K9,meta etc all before.
Out of those the Clifford and K9. I found the K9 to be just as good as the clifford and price for price more features. Just depends if you want Clifford stickers and fob.
I do really like the clifford alarms but iv been told they are really difficult to fit and programme.
Iv got a corba on my Glanza but iv never been massively keen on it.
the problem with someone else fitting your alarm module for you is that they have the lo-down on your setup and can always disable it or divulge that information about it. the perks of being a d.i.y'er is that you get to pick what cut-outs and fail-safes to build into the system..
