Just a matter of looking around till you find something. Ebay, Gumtree ar4e good if your trying to find something you like..
As for new. Shapers are always good and the Dion fins the boys put up are great fins at a great price..
shapers.com.au/box-fins-1/ Or you can go the top of the line jobs from Alkali, Soar, Captain fin, McTavish. Usually hand made.
Even surfstitch is ok when they have a sale on... The TCSS ones are pretty nice fins.
Or the FCS basic ones are pretty cheap all the time.

Maybe something like this 10.25 Tyler warren or one of the 11" ones from Shapers.
