I have the same and agreeI bought the A&D FX-120i , auto throw / auto trickle with all of the Area 419 goodies and now wonder why I waited so long to get it. It's a little pricey but worth every penny. The one thing I'd change if I was to do it again is not get the Area 419 powder throw with the glass hopper. It's pretty heavy and sits on top of the wind shield which just sits on top of the scale. I think the 3D printed mount would have been adequate for my needs. I do wish they would use a better powder throw.
I shoot from 100 to 700 mostly ,shoot out to a mile in the winter seasonThe Op didn't specify what kind of shooting you do, so the best answer depends on that.
If you only shoot inside 300 yards, then just about any scale under $100 should do it. Lots of very affordable options on ebay that will do just fine.
If you like to shoot long range, then cost can scale up rapidly depending on your expectations.
I've been involved in F-Class for about 20 years and have migrated from Sartorius to a Vibra HT 4 decimal place model which is beneficial if you want to try to hold the 1/2 MOA bull out to 1000 yards.
I know of no scale that is better than a Vibra.

I also use an Omega powder trickler to get within 1 kernel.
I would strongly recommend that you avoid the RCBS Chargemaster (or similar) because for the added cost of automation you are simply better off to by a set of Lyman powder scoops and a better scale. The automation seems convenient at first glance but it will never weigh the charges as accurately as a dedicated scale for the same price.
And herein lies the problem with a cheap scale, you just cant trust it for consistency and without a better scale you cannot validate it's accuracy.
I love my A&D FX120i but i am faster with my fingers than the trickler is. Dump a load, put it on the scale and drop a few kernels to bring it up or down to target.I bought the A&D FX-120i , auto throw / auto trickle with all of the Area 419 goodies and now wonder why I waited so long to get it.
