Does anyone with wordpress ecommerce sites take credit cards?

I was just wondering, because it seems like all the sites I have seen that use a wordpress e-commerce solution take PayPal only. Which is fine for those who don't have the volume to justify spending $30 a month for PayPal Website Payments Pro (for example).

If one of the plug ins hooked up to PayPal Website Payments Pro that would be ideal because it's the best credit card option for people ramping up because it is only $30 a month and there is no set up or contract or minimum order. But if there is an alternative that works with any of the plug ins I would love to hear about it!

Thank you!
