Pay To Blog, or Supporter?

I'm starting a new site. Everyone will have to be a paying member to blog and all members get the same package of features/plugins/storage. It seems that Pay To Blog is simpler to manage than Supporter. I've got Supporter installed right now but I've noticed that people can still get to their dashboards after time runs out, I don't want this. For my scenario am I better off using Pay To Blog or Supporter? The screenshots of Pay To Blog show even dollar amounts, can there be cents, $7.95 for example?
