Switch window to other screen?

My old work PC had an application running which added a small < button to the menu bar next to the restore, min and max buttons which, when clicked would move that window to the adjacent screen.

Is there an app like this for OS X? I'm really looking for something I can evoke with a keyboard shortcut like spaces that simply moves the selected window to the same position on the adjacent screen so i don't have to constantly leave the keyboard to move windows around.
