Here is a Photoshop spritefont template (PSD format).
You need CS3 or better to open.
This is the 16x16 version: http://www.gameus.de/c2/spritefont16.psd
This is the 32x32 version: http://www.gameus.de/c2/spritefont32.psd
(but you can change size you need)
To change the color or the font just select all text objects and change the style (color, font, opacity, ...)
To change the effects change one and copy the effect to all other.
A nice font page is dafont (http://www.dafont.com) (most are free for private or commercial use)
Probably some special fonts needs adjustments in the template!
