Hunting For Other Planets

All stars have something orbiting them, but it must be detectable, as
current technology defines that.

Out of curiousity in regards to the search for Extrasolar planets, why
are planet hunters studying worlds hundreds of light years away when we
have several star systems in our own back yard that don't seem to get
much attention, and in theory wouldn't their closer proximity make them
easier to search for and study possible planets?

Firstly we have the Alpha Centauri system a binary system and to my
knowledge planets have been already confirmed in binary systems, we
have Barnards star, Sirius, Fomalhaut, etc.
