Blake,
Allelectronics, surplus electronics dealer at 
<http://www.allelectronics.com>www.allelectronics.com, has high voltage, 
1600 up to 2000v, poly caps for VERY reasonable prices. The drawback is 
that they don't say who the manufacturers are so you can't tell if they are 
the ones that are on the "approved" list. At 8 for a $1, they still might 
be worth trying. I'm sure someone on here will have some opinion on this.
I have a possible solution for you. The Electronic Goldmine, surplus dealer 
at, <http://www.goldmine-elec.com>www.goldmine-elec.com, has poly/foil caps 
rated at .003 mF at 35kV for only $1 a piece. You can build a really nice 
cap with a very high voltage capacity by stringing together just a few of 
these. I feel sure there will be some feedback on this idea as well. I hope 
this helps you. I work off a small disability fixed income and I certainly 
sympathize with someone on a tight budget!!! I hope someone comes forward 
with some advice on my suggestions. Good luck.
