Decent, accurate, long lasting scales

Recently, my Tanita scales gave up the ghost on me. I thought it was just a low battery, but upon replacement, found the scales had gone to scale-heaven.
I decided to try some Salter ones, they dont even need a battery - they were solar powered - but found a terrible inconsistency of the weight. It sometimes fluctuated between 4 or 5 lbs difference in the space of stepping on and off again. Since then, have read many reviews of Salter that say something similar (on different models), so just for your note!

I can't find my old style of Tanita, so was thinking of getting a different brand, if I can't find any more Tanita - BUT NOT SALTER! Does anyone have any recommendations for ACCURATE scales? Available in UK. No more than £40....

Thanks all!
Tina
