I'm looking for a full featured font manager (support all formats - ttf, otf, ps, etc.). I use both Mac and Windows. The font manager does not need to be free but it does need to be under $100. Any recommendations?
I use Typograf which is a windows based font manager. $35.
Second vote for FontAgent Pro. I work for a print media corporation, and we use it all over the place for literally thousands of fonts.
I really am partial to Fontcase. Allows you to preview and compare fonts, along with a powerful tagging system. And it's only a bit over $50.
AMP Font Viewer handles/browses all uninstalled and installed fonts.
FontPicker is a handy comparative tool to compare installed fonts.
If you are mainly interested in reviewing your installed fonts the free Fast Font Preview provides a quick multi-line view, but doesn't review all types of uninstalled fonts.
