So I finally decided to lose some weight...I think I'm doing all right (given that my belt's getting a bit looser), but I really need to be tracking my progress. Any of y'all have recommendations as to bathroom scales? I'd picked up a cheapo one from Wal-Mart that was accurate to, eh, perhaps +/- 10lb, which seems slightly less accurate than looking at your gut in the mirror and guessing...I'm looking for something rather more accurate.
