Agree 100%. I just use a blade coffee grinder for my spices. No need for anything fancy, $10-$15 is all they cost these days.
Almost twenty five years ago, I was given a small Indian cookbook (Madhur Jaffrey, of course, her Spice Kitchen) bundled with numerous spices. It was a present from someone who knew how much I love Indian cooking, and love to cook, so it seemed a perfect match, and indeed was.
