I generally prefer Paypal as the best payment processor for making any transactions online. Either be it receiving money from other sites or transferring money from my account to credit card, i think paypal is the best and easy to use. What do you say?
Let just say Paypal is a must these day as it's widely used all over the world. The others can be used as an alternative. - Dynashox -
I personally like 2checkout and use them for all of my projects......they are stable and more flexible than paypal....certainly more professional! Regards Chris
2checkout is the best I ever used. It accepts both PayPal and VISA/MC, has user-friendly interface and has its own affiliate program. So you can set your product to resell, or resell 3rd-party goods.
