There are many educational stationary shops near Appa Balwant Chowk (Location). For local enquiry, you can try these shops. You may or may not find the exact calculator, but I am not sure if they order on demand.

If you are able to get it online, you can do that too.

You can try Venus Traders (FC Road, Appa Balwant Chowk, Pune Camp Locations).

Try "Ebay Global buy".They take care of customs and all.You may get a good deal if you buy used one.

I bought one, last month from Venus Traders-FC Road, with 2 years warranty with a price tag of Rs. 3600.00..
