my 4-5" marble mortar and pestle was $25 at sur la table but I think you can get them cheaper. I use it for grinding small quantities of nuts and spices and it works great and is easily cleaned with soap and water.
Since I stopped grinding my own coffee beans I use my coffee grinder for larger quantities of spices, it saves a lot of time
