This is easy.
There are a few good choices in electronic scales. What are you loading ? Precision Rifle ? Shot shell ? Pistol ?
I have used several scales from Jennings including the JSR200 which has a good resolution and capacity. At $ 23, it is a good value. it reads to 0.1 gr and for pistol or shot gun loads, it will more than work. But if you, how should I put this, want more just because you can and not because you really need it, you probably want something with higher resolution.
Many people use the My Weigh GemPro scales. It has a much higher resolution but is also $125. Do you need 0.02 resolution or is 0.1 good enough?
I have a old Redding beam scale that has been tuned and will react when a single kernal of powder is added or removed from the pan. I rarely use it except for precision rifle loads or to double check the digital scale.
