Where to get Styroflex Caps?

Anyone know a good source for "Styroflex" (that's Polystyrene, right?) capacitors?
Every place I find has a very small selection, and i can find .01uF/10000pF just fine in 160V. But can only find 1000pF/.1uF in 600V, nothing smaller.

Why not use the 600V version of the 1000pF/1nF then? Will it be too big for the PCB?

The only thing I can think of is that the thicker dielectric in the higher voltage versions could alter the tone. But who knows, a thicker dielectric might yield a more pleasing sound, so leave no stone un-turned.
