I recently bought an EatSmart scale from Amazon. My old scale was giving me 3 different readings, sometimes fluctuating 10lbs lol. I love this scale. It's readings are always consistent. It also has a blue backlight and large numbers which make it super easy to read. It only does weight, no body fat measuring, but I wouldn't use that anyhow so this scale is perfect for what I need.
I have a Tanita scale, have had it for over a decade and it is always accurate, I also love that I have NEVER in ALL those years had to replace any batteries or anything !! So it's saved me money also over those years. I can't recommend this brand enough. Body fat I don't think is accurate but it IS accuarate at watching progress if you just take the first number it gives you.

Mine was around $200 when I brought it 10 years ago, now my model would probably be worth around $50 by today's standards and newer better ones out there. So worth it though. I love it.
