I prefer the dial...it is more accurate, IMHO. I had a digital forever, and found exactly what Peggy said...the numbers would flip around. I wanted something that I knew I could trust. There are some good ones at Wal*Mart for pretty cheap...ours was a nice one and I spent $35.
Kelly, if you belong to any kind of gym, you can use their scale. Otherwise, see if there is a doctor's office near you that might let you use their scale...if you have a friend who works in one, etc, you might be able to do that.
