Need some decent free replacement fonts for your system?
First the Redhat liberation fonts. The liberation fonts give you a free alternative Sans, Serif and Mono.
My personal favorite is the
Bitstream Vera font family. The Bitstream monospaced font is really nice in my opinion and I primarily use it with my text editor when writing html or programming code, such as PHP. With a monospaced font, columns line up since all characters are the same width and spacing. This Bitstream mono makes “Courier New” seem absurd.
