 Do they offer any explanation for why a 30kV -at- .1uf cap is a few bucks
cheaper than a 25kv -at- .1uF?

 As for the quality of Plastic Caps' BNZ series, I can second the votes
given by Bert and Jeff.

 This is the line of caps I used for a series of commercial Tesla coils.
Over the last few years, DiaboliCo sold 4 or 5 (I'm not sure- I don't work
for them any more, I just consult) 12kw floor standing units, about ten 1kw
floor standing coils, and perhaps twenty 450watt table top coils.

 These coils have seen very hard use, being run every few seconds for five
hours a night.  I haven't had a single service call yet.

 Oh BTW, the small table top units use 15/30 NST's with much larger than
resonant caps, and the gap across the NST.  All are still in service with no
failures to date.

 In fact, the only NST failure we have yet seen was an early style of
Jacob's Ladder with the tranny in a wooden box with no fan.
