I switched from a Hario to a Handground a year or two ago and am very happy with the switch. It seems a lot more durable and consistent at all grind sizes than my Hario. Although, I do think Hario has improved things recently.
I use a Hario Skerton Pro, it's a good improvement over the o.g. Skerton. Be careful using a drill on it, though. I wore mine out and discovered i was grinding plastic into my coffee.
