which payment providers to integrate after 2co, eway, pp
We have a hosting company but this request is for another e-commerce enterprise. It's an AJAX cloud shopping cart in BETA for noobs, end-users, solopreneurs, users like that. Very nice and simple to use. Anyway, we're building in the payment provider modules and we've got paypal, 2co and eway (early cstomer request, i think they're big in oceania). Worldpay is next.
So - what comes after that? What other providers would you suggest to add and in what sequence? What are the "Big 5" of the payment provider world? We have Authorize.net, and Molpay (Southeast Asia) Alipay (china) already on our list. We just don't have priorities set yet.
Until recently I would have said Google Checkout, but that's being EOL'd soon.
Sagepay (formerly Protx) perhaps? They're popular.
A lot of banks offer their own systems, can be popular but very region-specific.
