-Seeing what appears to be the gearbox being made out of some sort of plastic/nylon is a mechanical turn off... Likely is totally fine for how it's being utilized, just not digging it...
I wouldn't comment on the other two as they are personal preferences but this one about composite gearboxes (I can't say too much about the actual design and material combinations) deserves at least some comment. You may have a preference for metal gearboxes, however they are not always the correct option depending on the type of gearbox and application and lubrication requirements. This is an epicyclic gearbox which spreads torque box (and multiplies it) throughout the box very differently to non epicyclic boxes. Composites are absolutely the best choice for this grinder, likely to have been more expensive than metal, give a much longer service life, not require constant re lubrication, far quieter, with shock loads and stalls handled better..Martin is a real expert in this type of gearbox design!
Rather than take what I have to say on trust, do your research on the web and you can find out for yourself.
P.S. A all metal epicyclic gear box would have been a very bad choice for the grinder
