Why not get an old Tektronix or other analog scope, they're a lot easier to use than a digital scope, well at least for a beginner. What sources do have in India for second hand scopes? I had a quick look on Ebay India, most stuff seems to be sold from the West. I have this vision of India having lot's of second hand electronic shops, not sure how true this is.
The only other way for you to get a better deal I can think of, is to ask a relative who is visiting USA or Europe, to bring one back for you. Good luck.
