I've never been with Epoch, thank the lord.

I started with CCBill 7 years ago and, in order to save some money, got my own merchant account and started to use Netbilling. But CCBill provided so many more services and more powerful reporting that I went back to them in first position.
I still use Netbilling as a second position and for my online DVD store. But I can't say enough good things about CCBill. They're big, stable, and supportive of the gay community.
