Searching for a "QIBLA NUMA"

I am searching for a good quality electronics Qibla Numa for checking the direction of Qibla. Do some body knows any shop in Lahore to buy?

many mobile applications are available for free todownload for your symbian or java based phones.

Do you want a stand alone Device or will a mobile application suffice?

It is better a 100% correct stand alone device. I am not sure about the accuracy of mobile's Qibla Numa.
