This is the one we use for tx weigh-ins... https://www.itinscale.com/easyweigh_px_digital_scale.htm... and you'll want the PX-60-PL model... and wouldn't ya know.... they put the stinking things on sale for $150. You can't beat that.
The batteries last for a long time too.... It was fully charged when I got it, and in the 3 months I've had it, I haven't charged it yet. But I will now because I probably just jinxed myself.
