There are lots of cheap chinese MKP caps on ebay that are worth while experimenting with and testing for tesla coil use.

If they prove durable, they very well may be a good option, but i dont know what the ESR would be like on them.

Another option that's a little smaller than the beefy GTO caps is running a string or two of the IGBT direct mount snubber caps in series. I have successfully used two strings of the 2uF/1kV Aerovox snubbers (see Link2 ). Can be picked up as used surplus very cheaply (I paid $100 USD for 50, shipping to NZ cost more than the caps!)

I just bought some of these, you or someone else might find them suitable.

NOTE: These are all glued using silicone adhesive, a real pain in the ass to remove.
