I really authrize.net since they don't care about the 2nd tier setup. Plus it works great with BFM.

I do like the leverage of clickbank but now knowing your affiliates can be a problem. This make is hard to use them for the next launch. But people love it and they do make life easy for some people.

I have used paypal payments pro with 1 shopping cart on a number of sites and it works great.

PayDotCom is something I don't like or use. It seems flakey to me. Glad I'm not the only one.

2checkout needs some work I can't ever figure out what I'm doing.

Thanks
