Where to stay and where to go in Costa Rica?

So here's the deal, plane tickets from Mexico to Costa Rica are about $100 USD, that's pretty cheap, now, we want to go surfing, probably staying in a good spot where we could just walk to the surf beach, or take a cheap ride/rentals.
We have been researching and we have found many "Surf Camps" that seem crazy expensive if you compare to the plane tickets. I mean, they charge about $1000 USD per person for a week and include all kinds of stuff we don't even need or care about such as Yoga.
We just want to hit nice surf beaches and relax for cheap. What do you recommend?
