Okay, I swear this isn't an advertisement, there's no referral code in this link or anything, but I've had this bathroom scale for a year now, and it's the most accurate scale I've ever owned:

It matched up with the WW scale perfectly, to the point I just stopped going to WW, since most of what I got out of it was an accurate number every week.

I know some of us were talking about this model on the boards last year, but they were sold out for a while... I just checked, and it's back!
I really think this scale has helped me a lot, I'm so anal about the numbers when I'm calorie-counting, and my old scales were soooo frustrating giving me different numbers every time I stepped on!
