I have a Dillon Terminator that was awesome until it will no longer hold zero. You can zero it out, check it a few times, make sure there's no airflow in the room etc. Set it to your desired charge, load a few cases, then reset it to zero and its off. Then when you rezero it, check the few rounds you just previously weighed and dumped, they are off .1-.2 of a grain. I am very particular and this thing won't cut it. I even took it apart, flipped the bearings around, cleaned everything and nothing changed.
I have since bought a new RCBS 10-10. I loved it at first, but I am starting to dislike it. It was made in China, and you can tell. The line on the beam and on the scale, where you check to see if it's zeroed out, are not very precise and it takes a little extra time to double check it. It also takes about twice as long to settle down when you place the pan on the beam. My Dillon is still twice as fast, I am not in any hurry, but the beam moves up and down for awhile until it finally settles. I might just be over critical about it, but going from using the Dillon for the last 7-8 years and to this is hard to get use too.
My advice is get a new old stock or good condition Lyman, Redding, RCBS, Ohaus, etc. off eBay or on a forum like the others have suggested. I have used some of these old scales before and they are the best beam scales in my opinion.
