Getting the right scale??

The scale I use can be off by 4lbs and if I weigh myself 3x I'll get three different readings. I'm currently using a Taylor scale that looks really nice, but it's not a good product.
So far my research has led me to EatSmart Precision Digital Bathroom Scale w/ Extra Large Backlit 3.5" Display and "Step-On" Technology and it's only $29 dollars about $35 less than what I paid for the Taylor. Anybody using the EatSmart Scale??
