hi!
I have pulled all the strings (and ropes) but all i get is to contact the local distributer, i.e. contact someone in india from pakistan who has only given his phone and fax number. I think it will be cheap that instead each time i call there i should purchase a chip i want from digi-key.
I have also contacted one of biggest local electronics component seller and tell him that i want few chips of Taxas Ins. each cost $1.02. He replied that first of all it would take 2 to 3 months to get any ordered chip, second he said that atleast 10 chips can be purchased and each of them will be of $5.
So, i think that digi-key is the best option i have. But i haven't check it yet. By the way can you guys tell me other good sources like digi-key.

Thanks!
