One reason we drink coffee, aside from the possible caffeine jolt, is for the flavor. Coffee aficionados know that flavor is both heightened and fresher when grinding whole beans right before brewing. It's possible to hit that sweet spot with just a small investment. Cheapism.com sifted through expert and user reviews to find the best budget-priced coffee grinders under $30. While all of our inexpensive top picks are blade grinders, we've also found a few entry-level burr grinders topping out at $50 that will appeal to coffee lovers looking for a finer product and finer ground without having to pay a premium.
