+1 to RCBS 10-10 scale.
I've been using one for a few months now and it's great. No warm-up time, no dead batteries, and the scale stores all of its parts safely when not in use in a clever integral case design.
I had a RCBS digital scale (made by Pact) and it finally became unstable. I've read this occurs after some time with digital scales. The strain gauges are set in epoxy and something changes after 5 years or more. Sometimes the mfgr can repair them, but it is often cheaper to just replace the scale.
I've never had a "high end" digital scale, so I don't know if these are any better.
What I know is, when I needed a new scale, I "weighed my options" and went with a mechanical scale.
