Perhaps a TO220 packaged resistor (or it's brother, the TO247) They can't
quite dissipate your 150 watts, but a couple in series certainly could.
Digikey has them in singles for about $7 (dropping to about $4 in qty)

Also, why the requirement of a full pack? Is mica or a sil-pad not enough
isolation? I don't see how a full pack gives you better safety than a
sil-pad and shoulder washer. - either way you still have the leads with as
much exposure as the tab would normally have.
