Hmmm 200 soles for an electric or acoustic guitar?
you might wanna look into the asian brand names (StarSun, Mekse, california, etc)
but those are usually in stores at Plaza 2 de Mayo. (Not great just OK)
Cantuarias, miraflores and plaza san miguel sells mostly well known brands
(fender, cort, ibanez, ovation, etc) and those never come cheap...
There are also peruvian guitars but I would avoid electric peruvian guitars
however for a classic guitar a peruvian one might give you a pleasant surprise,
even the cheap ones if you look really carefully...
