I bought the cheapest digital scale I could find at Walmart at first because I didn't know whether I would get into the habit and didn't want to waste a lot of money on something that would end up in the back of a cabinet. It cost about $15. (Definitely go with digital!) That was a year ago and I still use it everyday. II have had to change the battery once in that time. it has two simple buttons on the front: ON/OFF/TARE and UNIT(which changes the units of measurement). I have since purchased another, more complex scale (we need two because my husband weighs his food also and it keeps us from getting in each others way a lot of time) but even with more functions to choose from I still only use the same two buttons! Lesson learned! You will love it once you get used to using it. It is much more accurate to measure servings by weight rather than by the "piece."
