If 44kV is good enough for you, there's this listing currently on=20
eBay for $200:

There are rectifiers that come in cylindrical packages with a stud on one
side and a threaded hole on the other, so you can just screw together as ma=
ny
as you need. For example, 10 x 5kV. SDAD103 H 5.0 F  (3" diameter=20
x  1" for each knob)

There are also mercury arc rectifiers but you probably don't want to get
into that kind of thing- they can contain enough mercury to keep a
hazmat team busy for some time.
