Burr grinder is a much better option to avoid random sizing.
Otherwise, the best option is to hint to your friends or family that you really could use a Burr Grinder for your birthday or christmas.
Hand grinders often cost as much as Burr Grinders. It might work for brewing for just yourself but not for a group wanting coffee.
