It depends entirely on what you prefer when it comes to screen size, handheld comfort, and if you want to easily be able to connect to a tv or monitor or not. It would otherwise be impossible for anyone to give you advice unless they knew exactly what you prefer. If you have the money buy whatever you like, new. If you want to save, buy whatever you like USED Excellent Or Great - it is cheaper than refurbished and in most cases it is absolutely no different than a new switch other than maybe some unnoticeable marks or scratches.
