Which one is the best payment gateway in India for a new businessman?

A lot of payment gateways are there in India . selection depends on you like how much money you can spend for a payment gateway , size of business, which payment options yo want to implement . because a big payment gateway becomes more costly initially. So I would suggest to use small payment gateway initially like emvantage discussed above yogesh or many more but still you should confirm first , not take decision by one's answer.
