There have been relatively few discussions in English regarding this entry level grinder from Taiwan. There have been discussions on grinders of this style however:

The Costco in Taiwan carries the Yang Chia/Feima 600N. There are several versions and colors of this grinder, with cutting and ghost teeth burrs; typical of Costco, it is available as long as it is black. The ghost teeth burrs can be purchased separately from other vendors. For approximately USD$80, I picked one up at the Taichung Costco and figured if it is not good, I can always return it in the US with Costco's generous return policy.
The grinder is 110V and uses about 150W.
Over the years, I think the manufacturer improved on the burrs and the spring, so the burr wander may have been improved.
I'll be using this grinder over the next weeks and post updates prn.
