Acculab used to be pretty good. They suffered from a little drift and were sensitive to static in the air, or even the lightest draft of wind would make them "hunt" a little bit. I still have an Acculab 711 that is damn near brand new. I don't use it anymore.
Vicom 123 took over where Acculab left off, and I have the VIC123 which is perfectly accurate, has a glass static shield and works great, but it still drifts a bit if I leave it unused for more than 10 minutes between throws which is rare. Accurate to .01 grains. The VIC123 is now discontinued as are all of Acculab and Vicom scales.
The Sartorius AY123 is basically the same scale as the VIC123, and will have the same accuracy as the VIC, and come with the same drift problems, but if you can control your space while reloading, you will be very happy with it. The only real changes are plastic color and a few other cosmetic changes. It may in fact have some minor electronics updates that help with the drift issues but I am not 100% sure on that yet.

As a side note, Sartorius is world renowned for building accurate balances, and as far as I know, still holds the Guinness World record for most accurate balance. They know a thing or two about how to make these things, and for $335.00 you will be hard pressed to find a scale of this ilk to be any better.
You really need to step up onto a higher plain to get more accurate. And by that, I mean that the technology is fundamentally different when you get into lab quality stuff which is capable of accurately measuring down the the micro or milligram.
