Hello,
Mail Order Wizard has an extraordinarily friendly user interface. Since Wizard is DOS-based, navigation within the application doesn't require that you repeatedly stop what you are doing to reposition a cursor. The mail list management program is solid and easy to use; order entry provides for a variety of shipping, billing, or mailing addresses; order tracking is straightforward; items are easy to set up. The system is extremely stable - I can't remember the last time it crashed.
