List of Payment Gateway Providers For Ubercart/Drupal

Today a customer of mine was looking to find a merchant for his website and we wanted to find one that already a payment gateway module for Ubercart inside of Drupal 6.  As I googled I was surprised not to see such a list already compiled. 

So here is just an initial list I have drawn from tonights research, if you know of other modules that I’m not aware of, please add to this list, or add in a comment so that other people can benefit from this.
