Which scales do you use?

[Straitjacket]

I have some cheap ones I got a few years ago (although they have barely been used). I just weighed myself on them and didn't think it was right, so I moved them into another room and got yet another reading. Tried it again in another room and yet again, another reading. And not just by a few lbs! So, I am after scales that are pretty accurate.

Any suggestions?
