Having used one for a number of years, I frankly think you can do better, unless the early flaws of mine have been addressed. In addition to the ledges, the bottom of which I fixed by cutting a section from a plastic funnel and inserting it above the upper burr carrier, mine had these flaws:
The burr carriers are pot metal, not brass, and neither the threads nor the burr alignment are as precise as they really need to be.
The steps as delivered are way too large, and don't correspond in number to the marks on the housing.
The burrs are twice as expensive as others of similar size and quality.
I still keep mine, heavily modified, for the occasions when I need to grind half a pound at a time for my big vacuum pot, but otherwise I don't use it much. At $125, we could talk. At $300, I think better is to be had.
