Future and FCS brand name fins are expensive as shit. I personally like Captain Fin because they're still brandname but they're $15-$30 cheaper than the big boys. Plus I like how they look and feel under my board. that's what matters the most.
Ho Stevie sells thrusters for like $30. Some reviews say that the futures tabs are a little bit too big for the boxes and some people have to sand them down a little bit, but that's the price for saving $60 i guess :)
