this market is more turistic but you can get has incredible prices for everything
Paharganj is full of shops. Anything you can imagine, is there. if you spend some time you can find leather craftsmen in the back of the streets. Anything you see in the western hippie stores it will appear in Paharganj, incense, bed covers, copper statues, music,...but if you are looking more for clothes travel to Pushkar ,is better because you can choose more.
If you need jewlery or precious stones go to Jaipur.
