Nope, I'm in same boat as you. I have the 400 and the white hand held and they are about 10% different. I eat pretty well and am in phase 3 of P90X so I'm inclined to believe the hand held which has me in my mid teens is more accurate than the 400 which has me near 28%. It really sucks that it is off that much.

I think for the HBF-400 the body fat percentage just scales with your weight according to your gender, age, and height. I don't think it actually tests body fat.

What is this other scale brand that got it so accurate though, may I ask?

I've used mine, as well as the same one owned by a friend and I always have this issue as well. Even when I'm down to my lowest weight and have a six-pack and veins popping out on my arms, and legs with a BMI right in the middle of normal range, and after a trainer used calipers and measured me at 6-7% the body fat percentage on this scale has never dipped below 20 percent. At a heavier point (winter weight haha) I've switched immediately from a handheld that measured 11% to this one which gave >23%. Makes no sense.

I read that the method these scales use to measure % body fat (bioelectrical impedance analysis) is highly inaccurate. The best you can hope for is spotting trends over time (i.e. does % body fat decrease over a longer time period). The fact that you have to give the machine all kinds of parameters (height, age, fitness level etc) clearly shows that the machine is not measuring your body fat, but is using a mathematical algorithm to come up with an educated 'guess' what your % body fat might be.

With BIA it only factors in the mass that is being measured. So, if you have a handheld, it will measure the upper body and torso but a staring scale will measure from leg-to-leg. So depending where you hold your fat, it can be significantly different between hand held and leg-to-leg readings. A con of BIA.
I hope this helps.
