Durability
Keep in mind, it's not just about the quality of the grind vs the price. The durability is important too.
Cheaper units have more plastic parts, which wear down faster than metal ones. Coffee grounds themselves are mildly abrasive. Grinder designs that use plastic impeller (the part that moves the ground coffee beans toward the container) eventually fail because the impeller gets worn down and stops doing its part, resulting in the grinder plugging up.
