Macap with doser.
Ive been happy with mine.
I also have the Sunbeam and no exactly what youre going through.
I got mine as a grinder for work but have since replaced it with an MDF.
The MDF is quieter, not messy and if you know how, doesnt leave grinds behind. What I put in I get back.
Back to the Macap.
Quiet (anything is next to the Sunbeam)
Quality to last a lifetime.
Sweeps pretty clean and if you remove the finger guard you can brush the last few grinds out of the chute so theres no wasted/stale grounds.
The Macap ticks all your boxes.
