Yes, it is a shame the old reliable GemPro 250 went away. That one fit the bill for many folks but it was discontinued and the succesor doesn't really work for trickling. Be very careful not to just grab something off the internet unless you know it has been recommended by reloaders. Many cheap digital scales do not respond to trickling.
I would still consider a type and style you didn't ask about, as in a ChargeMaster Lite and a rechargeable battery pack.
Many BR folks run these without any additional wind break because it is built into the unit. It isn't hi-resolution like an FX120 or anything like that, but for 600 yards and in, it does fine.
All of these styles and systems have their quirks, and the ChargeMaster Lite certainly has some of its own too, but for the money and value, it does a decent job in the field. It is very common to see these at BR matches and with folks that run load development in the field.
I have gifted several to folks starting up, and still run two of the older style machines when working at the range myself.
These do tend to have over-throws and like anything it takes a learning curve on how to set up your work flow to keep the frustrations to a minimum. Strong winds and rapid temperature swings can happen, but you learn to keep the machine as sheltered as possible and check for calibration and zero drift regularly. As long as you are okay with an uncertainty of about +/- 0.1 grains, you can run with one of these, and something like this battery pack. The Y-harness plugs right into the ChargeMaster and you are off to the races.
Semper Fi.
