Mantech Electronics is probably the best component supplier in South Africa. With brances in Johannesburg, Cape town and Durban they deliver any where in the country. Their service is unbeatable, one can even request to bring in hard to get components not locally available in from anywhere in the world. Delivery is on a daily basis, no order is too small or too big.
Although they are not official distributors of pic microprocessors, they do stock some and probably keep more stock than the official suppliers. They also supply Pickit and ICD programmers.
