We just got one at work, and I've started tracking myself. I was wondering if anyone had anything to say re: its accuracy.
Some of the numbers it gives me makes me wonder, but, being a light weight powerlifter, I tend to train different than most people. I train for muscle density which means I hold less water in my muscle fiber than the average lifter who's constantly trying to put on more mass. I was wondering if that could throw it off a little, or if this thing is good enough to actually be accurate.

As with all bodyfat-measuring scales and devices, accuracy for the Tanita is dubious.
Precision, on the other hand, may be reasonable. This means that you may be able to use the scale to monitor your progress (is your BF% going up or down, and by approximately how much?) but not your exact BF% number.
I commented on a similar issue previously on PaleoHacks, and Mark Sisson has commented on this too. Basically, don't worry too much about the exact number you get. It could be off by a lot, as much as 5-7 percentage points, perhaps. But, if you see a consistent trend over repeated measurements, that's information that may be worth having.

I have a BC-1000 unit. What I have noticed is that body fat measurements change by as much as 2 percentage points between an early morning weight-in and later in the day. I'm not sure why this is.
As to accuracy, i have no idea, and i would be cautious, but I agree that trending is a good indicator to look at.

It is very accurate at measuring weight. It is not very accurate for body fat %. However it can give you an indication if you have increased or decreased your body fat % and in fact may be accurate for some people (depending on your size and body comp).
