the terumo woman-c can be set to not beep. it is $45 on amazon and the instructions need to be run through google translate (japanese). though several of the amazon reviews have instruction synopsis as well. it will store the temp as long as you set an alarm time to take it, and take your temp within two hours in either direction of that time. so 45$ gets you a celcius thermometer with backlight and a silent function, that stores a yers worth of temps.
