I've only used a couple blade grinders (think like a $19 Hamilton Beach grinder) so I can't speak to if there are any super fancy ones, but it is inherent in their basic design that you won't necessarily get uniform coarseness from the grounds. The blades chop up the beans basically at random as they fly around in the grinder. Compare this to a decent burr grinder (like a $99 OXO) which the beans all fall through and get caught in the burrs in the same way. $80 is a big difference (to me, anyway), so I feel bad suggesting someone else spend that, but I can say I taste the difference between the two, and I've made up for it with the fact that I no longer feel the need to treat myself to a nicer cup of coffee from a coffee shop on a Friday morning. The other benefit of getting a burr grinder is that you can dedicate the blade grinder to whole spices. Having a little residual cardamom in your coffee might be agreeable, but that's not the case for cumin or cayenne. :) Good point about the beans. I didn't think about that because I've been buying the same beans from my grocery store's bulk bin for years. These same beans have seen every grinder and brewing gadget that's come through my house.
