I picked up our Angelcare as new at a kids market for $60 and another older one for $10 at a trash & treasure market. Would have bought a new one at full price if I didnt't find the market one. The good thing about the sensor monitors is that they do alarm as opposed to the sound only ones that don't - how do you tell when your baby stops breathing? Not really relevant to the original post but I thought I would mention it.
