I've got good news!  Consolas, a cleartype font designed specifically for to make code more readable is now available for download for users of Visual Studio 2005 from the Microsoft Download Center

One important thing about Consolas is that it will only look good if you have ClearType enabled.  You can check the setting from the Display applet in Control Panel.  On the Appearance Tab click the Effects button.  Ensure the the check box "Use the following method to smooth edges of screen fonts" is checked and that it is set to Clear Type.
