What security systems should I fit?

[Steve_D]

This may be directed primarily at Simon as it is his field but is still of general interest.
I had it in mind to fit:-
1. An imobiliser. (Required by the insurance companies I believe).
2. An alarm. Probably part of the Imobiliser above.
3. A tracker type system. This is the one I am not sure about as there are now a number of them out there but I have no feel for which one is best.

What is recommended and what is everyone else doing?

Ted was pretty neutral on the whole matter based on the perception that it would be difficut for a thief to sell it on as it would be difficult to register.
The 'joy rider' aspect could be dealt with by the inexpensive use of hidden fuel pump switches and the like.
This thread could be interesting!!!!
