If you use MS products as part of your day to day check with your command for a "take home" license. I can't remember what it's called but MS used to allow normal commercial users a take home copy to install on their home PC. When I did it there was a website you went to, entered your command details and it spit out a license file. Burn install files and license files to disc, take home, install. And you could get just about any MS office products including publisher and other lesser used products.
