Hi, I am also an embedded systems engineer, and had a very hard time finding gadgets from local market, and had no choice but to buy these items at higher price.
But the good news is, I have found this website http://instock.pk based in Islamabad (Shipping all over the country), they have alot of new and updated gadgets at very reasonable price...
I have also ordered the items which were not available on their store, but they arranged the components with-in 2 weeks. and offered 5% discount on back-orders.
I would recommend this supplier if you are looking for reasonable prices and wide variety of components.
Sohaib.
