I got some fins from INDO Fins - ex-Bali on Ebay or you can order on their webpage.
Super helpful, quick service and good price.

I am sure some surfers may have thoughts on flex etc... if they are using them in decent conditions in but I got these for a small wave summer board. They are a great option too if you want to try something a bit different like keels without splashing out the full $$$.
Only problem for IFocus is I am not sure if they do futures compatible or just FCS.
