[TCML] Ceramic Caps

[Ben Sneath]

Hi all,
i'm contemplating building a .0026uf, 27kv MMC for my new
coil and was wondering how suitable ceramic caps were for
tesla use. the following link are the ones i'm thinking of
using:

Thing is, there only 75c each... they seem to be that little
bit too cheap
dosent say about their rf capabilities... 
anyone ever used these type of caps? power source is going
to be an old ac flyback transformer + the common 2n3055
driver circuit.
