There are quite many you can choose. The one Ibought for the rental house cost me only $10.00. It has two parts: one is door bell which you install inside the  house, another part is button switch which you install by door. You also can buy doorbell with mutiple switch buttons(front door or backdoor) and you can config them to have different bell sounds...Anyway, it is only tight screwer job. very simple and nothing hard.
