My personal favourite is the Western Caliber III - accurate out of the box.
I have 3 myself. A while back I tested with salt test to see how accurate they are. I also have the same one you mentioned as "worst". And yes, it is +5 from the actual reading. My other one is -5 from actual. My analogue one is calibrated to be spot on.
