I did some research on varies postage meters and decided on the Mailstation2 from Pitney Bowes. After the 2 month trial period, it's only $19.99 a month. We're able to use the exact postage - no more guessing. I also love no more trips to the post office. Even our certifieds are sent from the office! When I need more postage I just order it through the machine.
Stop by Pitney Bowes website for more information.
