Programmer's Font

Can anyone recommend a great programmer’s font?
(besides fonts like this: http://www.arcavia.com/Software/ProgFont/ which is a joke, because you can’t read this in a program OR in a sentance.)

how do you make it so you can use this font for the code view etc in DW?

Dreamweaver:

go to: Edit --> Preferences --> Fonts --> And finally change the font at Code View(default is courier new)
