But there are a lot more choices than just 4 payment processors.

True but look at the Bitcoin exchanges in the UK for example. You can hop between 12 banks and each one will close your account until none are left.

Doesn't bode well for the stability of the business.

We need a payment system which isn't Visa/Mastercard and preferably not US based.

Honestly, China Union Pay might just say yes to the business that those decline. If only they break into the international markets better...
