Do you need one for productivity or some other reason? The only reason I ask is because if it's for productivity from having more screens I stopped using an external monitor and find I am more productive with command-tab. I know there's a lot of purported research suggesting this should not be possible and most people may disagree but I really feel it's true for me and so if you can borrow a monitor for a while you may want to test if this turns out to be the case for you.
