Scales

I am a few weeks into my journey and I'm very thankful for all the advice with the recent FDA hubbub! This morning I was thinking I should purchase a new scale. I've had the scale for years and I've been wondering for some time when I hop on it why it shows the exact same weight down to the ounces. We know that our weight can fluctuate and having the exact same weight for weeks on end is Pretty difficult I would think! This morning I got up and I did hop on the scale and I was thrilled to see that I had lost 1.1 lb! I got my coffee and did a few things and decided I would shower before going out to do some errands and while the water was warming I hopped on the scale again and it went back to what I've weighed for weeks and weeks obviously I did not gain a pound 1 oz in an hour! I don't normally weigh myself twice a day by the way this was just me being forgetful! So what scales do you guys recommend?
