I looked at the TG6434 but went for the KX-TG7434B instead. Choicemail was the decider. It's everything they claim it to be and more. I can review messages from any handset. It allows you to listen to all new messages, to all messages, or to review a list of all the messages on your screen. You can play and delete messages as you listen to them, or you can review the message list and delete them from there, without listening to the message itself. Great phones and easy to use.
