I need a pestle....

Yesterday morning, as I was grinding a few cardamoms with my giant granite mortar and pestle, I decided that I need something littler, like a suribachi. My big Thai thing and my molcajete are both overkill for tiny grinding tasks. Then, on my way home from the store I found this cute suribachi in a pile of free stuff that hadn't sold at a yard sale the day before! I need to get it a wooden pestle, though, and I'm afraid it'll cost almost as much as an entire set.
