Recently, I bought a new Nokia 6030 
and gave my old Nokia 2300 to appa. I gave the headset which came along with the N6030 to Appa and retained the old headset with me. The old headset had been my buddy for the past one and half years and I have used him to the max. I used to shuffle among the FM channels with the cute remote in the headset. On Friday, he disappointed me and stopped working. 
I tried all my level best to repair him but found that he is gone and cannot be used anymore.
I decided to buy a new Nokia Dual Headset HS -7 and here is my experience on the search for the headset. Balaji used to say that buy at the local shops to encourage the local entrepreneurs and don’t go for big shops in TNagar or elsewhere. He bought his new mobile at one of the local vendors. I followed suit and went to the same shop and asked for a original Nokia Dual Headset HS -7 and the boy at the shop told me that it will cost Rs.350 for an original one. He brought a small piece of pouch which had a headset with the name Nokia but it had faded letters and I immediately found that it was a counterfeit one. Here is the conversation.
Me : It does not look like a original Nokia headset.
Boy at the shop : Are you looking for that original Nokia Headset? If so, It will cost you Rs.450 and you need to check out in showrooms.
Me : !@#$$% (asking myself) What is the difference between original Nokia headset and that original Nokia headset?
I tried in a Nokia priority dealer and they did not have a stock of the one I was looking for. Finally I tried to enquire a shop at Tambaram. The guy at the shop told me that he can get me the headset but it will cost me Rs.650. When I asked him to show me the headset, he told me that I need to give him Rs.650 and he will tear open a new Nokia 6030 box 
in front of me and give me the headset alone. I was shocked to see his response and left the shop immediately. There was another shop keeper who asked me to go to the Nokia Factory to find the headset I am looking for. I have a few questions in mind after the search.
1. What will the guy, who promised me to tear open the box, do to a new customer who buys that phone?
2. Why does not Nokia beat these counterfeit products by selling the original ones at nominal rates?
Till my search for the original headset ends, I am left handicapped without my headset and with un answered questions. 
I’m against your brother’s suggestion this time. I always make a point to got to the original brand showrooms to get stuff inorder to get the original ones with proper guarantee and price etc. I dont mind shelling out extra money if there is a guarantee or if the piece is original. Another reason is my inability to recognise dupicate stuff and the right price.
I suggest u go to a big dealer and buy your head phone.
Umesh,
And by the way, I tried a couple of Nokia Priority dealers and they told me that the double sided headset I am looking for is not in production and I have the choice of buying a single sided one. Hope Someone has it in store. If someone finds a original model of Nokia Dual Headset HS -7 in Chennai, let me know. Millions thanks in advance for that someone. 
I think you mistook what I tried to explain or rather I should have put Balaji’s words more clearly. His idea is to buy original goods at the local shops to encourage the local entrepreneurs. He bought his new Nokia mobile at a local shop although he could have saved a few hundred bucks if he went in search for discounts in big shops. Hope this clears it out.
Karthick: How about trying ebay? You can post a want it now request there, if you don’t find it already.
Shikha,
Thanks for the suggestion. I will not buy anything in ebay India. I have seen some profiles in ebay where ratings are given in terms of mutual agreement. It goes like this. A person rates another “Genuine seller and prompt delivery”. The person goes and leaves a personal comment ” I have given you good rating and hope you do the same “.
May be the initial days of ebay India was like that. Anyways, I got my headset back from appa as he does not use it.
