I can definitely understand your position after that experience. Mine has been exactly the opposite though, and my electronic scale is pretty old. Maybe that is part of it, as in they don't make things like they used to. LOL.
I literally got mine from the widow of a BPCR shooter through my brother who knew her and her late husband. I thought I paid too much for it at the time, but her husband had just died after all and it did save me a few bucks over a new one. It was well used then, and that has been about 9 years ago. It has probably only had 2 or 3 batteries in it since I have owned it and the display blinks to give you plenty of warning that the battery is dying, but it does take a 9 volt and the new models sold with the same name now take AA's. It has the option of an AC adapter but I have never bought one for it. It's never needed a repair or ever let me down.
I even used it a few weeks ago for the first time outdoors, weighing all of the competitor's (appox. 200) bullets at the chronograph for the 2010 Mississippi Classic. I used a cardboard box with the bottom cut out as a windbreak. It bounced around more than normal before settling down, but with the time pressure to pull bullets, weigh them, and log the info before the squads got there to chronograph, it was still significantly faster than a beam scale. Most won't ever have to do this (I never have before and may never again), but the old digital is now back at home on my bench and appears to be working no worse for wear. Maybe I just got a good one.
