I have some old MFC 350 Quad fronts in my shed - little red ones with a narrow base and almost shark tooth style profile?
I'll see if I can get a photo tonight
these are the cheapest I know of and may need some outline changes

sanded have a similar one for $30 but it's sold out currently
Hey Mark, i have a pair of 8 cm K4 Rockets and 9 cm K4 Shark II. Located in Germany, shipping to Australia should be possible.
I should give a set a try. I prefer their more upright fins like the Leon and Stubby, I don't rate the Scorcher much at all. I have yet to try an Incinerator yet though.
