Steve --
I'm not too sure that I can honestly compare the merits of "botten" flakes vs grind your own, but here's an idea on spice grinders.
Before we bought our bean grinding coffee pot, we used a coffee grinder from the dept store. Once we no longer needed it, I claimed the prize and use it for grinding spices. It works great! Small enough to hold, while grinding, so you can shake it up and down to keep the spices going through the blades. Works much better than using a mortar and pestle -- which I tried a few times.
Seems like the price on the coffee grinder was about $15 - 20.
