The question of what type of balance to use for weighing powder in precision reloads is a common one. Different people have various choices in answer to this question, ranging in from tuned beam balances to expensive laboratory analytical balances. There are no "correct" or "incorrect" answers; whatever works for your intended application is sufficient.
If you're considering buying a good laboratory analytical balance, I would suggest spending the money to get a magnetic force restoration (MFR) balance, rather than one that uses a torsion or strain gauge mechanism. Unfortunately, they aren't inexpensive. One of the best choices at the low end of the price for for such an MFR balance would be the A&D FX-i 120 balance, which will cost in the neighborhood of $600-$700. Another excellent choice would be the Sartorius Entris 64, which will cost up to about $1400 or so. The price can even go much higher, depending on the selected brand and features.
I am a big advocate of purchasing the best analytical balance you can realistically afford. I have used less expensive strain gauge-type laboratory analytical balances in the past. That is not an experience I would care to repeat, even with strain gauge balances costing in the $300 to $400 range. The frustration one may experience with such a balance is simply not worth it, and I would simply recommend saving to buy a quality MFR balance instead.
On the other hand, not everyone's needs require a MFR analytical laboratory balance. So a good place to start would be to determine the level of precision your powder weighing needs require. Then you can begin looking at various powder weighing options that will satisfy those requirements AND fit your budget. You have to start somewhere, and defining the necessary level of precision in powder weighing is a logical place to begin. Further, there is no substitute for doing the research to narrow the list of potential candidates. Once the list is down to a few candidates, soliciting opinions at reloading forums on specific models/brands may be useful, but I definitely wouldn't start there.
Something else you might consider in the interim would be the Gem20 scale (

I'm not going to tell you that the little Gem20 is equivalent to a MFR laboratory analytical balance costing $700 or more. It isn't. I wouldn't realistically even consider it as a
long-term solution for weighing powder. But you can get one fast and it will do the job while you decide what type of balance you really want. Once you purchase your analytical balance of choice, the Gem20 will still serve as a backup in the event something might ever go wrong with the other balance (it happens, sometimes). For less than $25.00, it's worth it. I bought one after reading Boyd's thread and reviewed it with regard to precision (Post #63, p. 4).
