Eletronics Shops, New York City
Eletronic Shops in anywhere (most in times square), very unpolite people with not trustful merchandise. Complete avoid those little shops, don't even step in one of those (it will always be a bad experience). Always go to big stores.
Try for example CircuitCity near soho, they have good prices and friendly sales people there.
Electronics stores: Big tourist traps. Never buy from the 5th Ave electronics stores! Basically if it's not a chain like the Wiz or Circuit City, you risk getting ripped off real bad.
For photo equipment: There are only two real stores in New York, Adorama and B&H. I prefer B&H on 9th and 34th street. DO NOT BUY CAMERA EQUIPMENT ANYWHERE ELSE. You seriously risk getting fleeced, even if you think you know what you are doing.
If you are into the high end, expensive film camera equipment, Ken Hansen and Tammarkin are straight arrows as well.
Everybody know that electronics is not expensive in the USA.
When you visit Manhattan in the first time, you will see a lot of electronics shops, most of them at Times-Square.
The prices will look to your amazing!
But don't hurry my frined!
Don't be trapped!
Try to find a place far away from Manhattan...
Take a subway to Queens, find s K-Mart shop (large shop with everything: cloths, electronics, etc...),
this is the place where you will find things on very good prices. If you buy and want to change, no problems. They don't ask any questions. I even bought a raincoat there, and the same day I got few holes (I realy don't know how..) in the subway.
They give me my money back!
When buying electronical equipment in one of the many stores around Times Square, try to haggle with the shopkeeper. I bought a set of camera lenses, asking price was US$300, I got them for US$150 in the end. Be aware you may not be allowed to import equipment from the US into your own country!
