would you get one second hand from a wreckers ?
but, if all you want to do is plug in a charger, you don't need the big cigarette lighter connection. Find the 12V feed and fettle up an adapter that you can plug into. With only two wires to play with, (12V and ground) it is one of the easier jobs to do.
If you really want to make it neat, then buy a very cheap kit and make up an ipod charger yourself that you can plug the phone straight into or, easier still, buy a second ipod connector/charger, cut the cigarette lighter plug off it and hard wire it into the 12V wire under the dash.
To my mind, wiring the electrics through a cumbersome great thunking cigarette lighter socket isn't that elegant. It might have become the standard for all things electric that need to work off 12V, but there are better ways I think.
oh, and welcome to dolly ownership. It is a requirement of the forum that you post some pics up of your car

I'd be tempted to cut the 12V plug off this, wire it into the 12V direct, then you have two sockets (shudder
) and a USB (5V) connection
and a handy LED battery indicator which presumably tells you when the battery volts dip below 11.5V or something.l
