Commercial NNTP Gateway Recommendations?

plazman30 asks: "I am a customer of comcast.net, which provides usenet access through Giganews, but they cap downloads at 1 GB. Giganews will allow greater access for a monthly fee, but the amount of download you get is based on how much you pay. I am interested in getting usenet access greater than 1 GB and am willing to pay for it, but I want to get the best value for my dollar. I was wondering what slashdot users that pay for usenet access are using."
