MMC source?

	I haven't the slightest i dea what I'm looking for in an MMC, but 
this looks good...pretty cheap too! I have a NST 12kv/60mA, would I make like 
20 strings of 20 or somethin? I don't have a clue...well almost. Thanks!

They ran out of stock for the moment I guess, I just saw that, still, are 
they good?
