You will be able to do different things depending which style you go with (in vs. out). But for convenience (and initial cost) I would say start with an indoor and if you use it often enough and like it then upgrade later to an outdoor. We have both (and use both) and the indoor is nice when we don't want to cook a lot or the weather isn't cooperating. The outdoor gives you the option of cooking more things at once (veggies and meat at once) and you get a different flavor. We have a George Foreman indoor, it's great, and a Charbroil gas outdoor grill that we love too.
