I bought mine from Nick Osa in July for $15.75. Not sure what Bill is charging for them.
I can tell you that the ceramic guide blocks work very well. And they don't wear like cool blocks do. However, if using very thin blades (e.g. 1/8" or smaller) I'd use cool blocks because you can completely enclose the blade without damaging it.

Although ceramic blocks are not expensive, we have to remember, -- When using cool blocks it is necessary to flatten them and square them every once and a while.
If you use two sets of blocks, one ceramic and one cool, you have to remember where you put the last pair.
