It strikes me that the only reason to spend more money on any grinder is consistency of grind. It also strikes me that consistency is equally important whether you grind for espresso, drip or Caffetiere. I never drink espresso so i can't comment on that. All I can say is that I drink mainly drip and some Caffetiere coffee and this grinder works damn well for both. that said, I'm not really sure if I could tell the difference in the same coffee beans when ground for a drip machine on this grinder or on the most expensive one on the market - i'm just not sure if my palette could tell the difference in consistency. Caffeteire might be slightly different becuase you get that sludgy stuff at the bottom. My caffeteire stuff is really good - it may be better in a coffee shop - but again - i'm not sure I'd be able to tell the difference.
Therefore I would recommend this for any house. Naturally if you're made of money go for a grinder that will give you a better consistency but you need to spend at least $150 to make it worthwhile I guess, but if you don't want to spend that much I doubt you'd ever be able to tell the difference
