i was looking into getting another one of these. my first one recently died of old age.
Maybe its not meant for me to have one, i did take "Obsidian" for Granite. Of Quartz, i may change my mind down the road. it will be Tuff. i will have to start with a clean Slate. Perhaps i should wait until i move to Petosky. I heard Flint is nice..... isn't that some funny Shale.
