I would contact Aperion about matching the 422-C with the 532-PT's then, or maybe someone here can comment?
Are you using Mozilla or Foxfire? The Aperion website doesn't work well with those. You can switch over to IE to post - it will recognize the returns, and you will see many more features in the 'message' box as well. You can also edit you posts with IE, I don't think you can with Mozilla or Foxfire?
