Query: Good value for the money

I just got this grinder (well, it is an all black version) from Costco for $30! It works well (though the capacity is a bit low for beans, but I am not complaining one bit)! I am going to save money on coffee because it seems to produce twice the coffee through a finer grind than what is possible with a blade grinder. So, I expect to consume the same number of cups per day while my raw coffee purchases will go down, thus paying for this grinder in no time.
