bodyfat analyzer Question

I'm looking into buying a bodyfat caliper. To test my bodyfat with and my brothers and my moms. I'm looking at a couple of different ones. I'm thinking about getting a digital one. And I also seen this one on www.afaa.com
Can anyone tell me what they think is a good bodyfat caplier, so I know what to buy. This one looks like a hand held video game but sounds intresting.

Here is the description of it ---The first handheld body fat analyzer of its kind. Determines body fat with a press of a button by using bioimpedance technology to measure the body's resistance to a weak electric current. Each reading takes just seven seconds and the analyzer travels wherever you go. Requires no special training to produce accurate readings. Proven in three clinical studies to yield results comparable to the widely accepted underwater testing method. Includes AFAA's Body Composition Home Study (6 CEUs), shipped separately. AFAA approved.

I got this info. off of www.afaa.com

sorry here's the pic. of it.

"comparable to the widely accepted underwater testing"

I love vague terms...

If it were me I'd go with a set of calipers. The electronic testers are not very accurate. IMO.

What ever you decide on use them as a benchmark-even if in-accurate it will give you a relative measuring tool.

thankz for the help
