Bad scale what is a good one?

I have a scale that was around $20 but it is terrible. I stand on it once and it will tell me one number, I get off of it, stand back on it and the number changes completely. Lately I have just been averaging the number (pick the number that comes up the most). This is a hassle and I would like to get a good quality reliable scale.

Anyone know of a great scale? Oh and I prefer digital ones too.
