Hi Jonathan

Depends what you mean by cheap...  Philips produces the BY8400 series. 
Typical example: the BY8410 has V[RRM]=10kV, I[F(AV)=5mA and costs $1.80
(Australian) from Farnell.  The range goes up to higher voltages
(V[RRM]=24kV), but if you want higher currents, I can only suggest using
a load of low V / high I diodes in series.

Note - these diodes should be potted or used in oil - they're rather
small and would flash over.

Hope this helps.

Cheers

Matthew Smith
