Peru is home to a world class wetsuit company, Boz. (www.bozwetsuits.com
) they will be a bit cheaper than imported suits, and they are top quality. I actually know many people in California who use them religiously. Not sure about used ones though. I'd also look up Wayo Whilar, he is a top notch very experienced shaper and I've never surfed a bad board of his. Also, the Klimax surfboards shop on Jose Gonzalez around the corner from the Bembos on Larco in Miraflores has a selection of used boards as well as their own new ones. There are many more options but these should get you going for now.
