This on-line exchange service is free and has a geographically based listings search filter that is tied to a a specific radius from a designated zip code. It also allows a user to designate other Gigoit users as "neighbors" for easy referencing and linking. In addition, it supports using RSS (real simple syndication) to provide streaming updates on new listings. Finally, it allows users to link their Facebook page, as well as various Google tools (e.g. Google Earth) to Gigoit data.
