Search in internet for the site I mentioned for the earphones...
www.evolta.cl, I didn't see a s1mp3 of 1 gb of screen 1.5... just 1.8 which of course is better but a bit more expensive. $ 45.000 (US$ 82.)
The best is that is a established store and they can guarantee their products.
Anyway, in deremate or mercadolibre are lots of offers.
Good luck
