Any suggestions for surf spots in Chile?

Greetings, Gentlemen!
I stay in Lima now and think of going to Chile for surfing. Can you recommend me some place to visit?
I am not a complete newbie, but I need more practise. Here in Lima I standup my 7 feet board more or less confidently.
So the question is: which places in Chile I can visit? Or may be its better to go to Argentina?
