geolocation for CB

I am looking for a geolocation component for joomla and CB.

I would like users to be able to connect or find each other via address or zip code. I have looked around but I haven’t found any with good reviews or that even can prove they work.

I don’t mind paying for a commercial component or module.

Even a Dating site that I could reconfigure would be a start.

Any help would be great appreciated.

thx
:S
