There have been a bunch of budget milligram balance models ending in '123' over the years, starting with the Denver MXX123. They all seem to have the same internals, but also suffer the same problems of strain gauge balances, which are at their limit at milligram levels. They're not bad for the money, but a bit drifty. The next level is the 1mg A&D Fx-120i. These are great for trickling onto, responsive to slow/small changes, very fast settling and stable (zero tracking still needs to function though). I've had a couple of these for years, and built powder dispensers around them. I prefer them for powder weighing to my analytical (0.1mg) balance.
