Credit Card Processing for U.S.

Hi all. Question for U.S. Dolibarr users:

Just curious as to what others in the U.S. are doing for their Credit Card Processing. Are you just using the PayPal feature included, or have you found other credit card processors that work in the U.S. with Dolibarr? We currently use Intuit, but it will not work with Dolibarr.

Thanks!
