I want payment gateway for my website, i sell domain, hosting , webdesign.
I already have paypal and i want to add 1 more payment gateway, i am going for 2Checkout, As i am in India can 2Checkout will be a good option for me .

I want to also know that is there a limit in 2Checkout for withdrawing funds.

Yes, as for 3rd part gateways, I think 2CheckOut is a good choice. And there is no limit. They will transfer the money you make to you every week.
