Started out with a Frankford Arsenal that was surprisingly reliable for the price. Eventually moved to a Hornady Lock-N-Load bench scale and have been happy that I did. I've had it for about 4 years now and haven't had an isssue getting it to zero or calibrate. I calibrate it every time I go to use it - I do power it up for about 10-15 mins before calibration just to give it a chance to warm up so to speak.
