My Lyman digital powder measure finally died and it's time for a new one.  With Lyman, RCBS, Hornady, etc., which do you recommend and why?

My H is slow and often goes over. My R is faster and more accurate but not all the numbers work.

The A&D Fx-120i scale with AutoTrickler/AutoThrow is the best available, and it can reliably throw charges to +/-0.02 gr even with "difficult" powders; the downside is that it costs nearly $1k, but it's worth it.  If you don't need/want that level of accuracy any of the major manufacturers' units will do the job.  All of them have their quirks, so it pays to do a bit of research before buying.
