Definitely worth it.... I've had gates installed on two different properties over the years. One set wrought iron and the current set which are solid wood.
The other thing worth considering is a SIM controlled keypad. The keypad phones the house and then if no answer it rings your mobile. It means you can answer the gates from anywhere and open them if necessary. Possibly very slightly cheaper than having an intercom wired in.
Very good for deterring any 'casual' callers.
ETA - please do feel free to PM me if you want to ask anything about them.
