Well, if you've only 200 or so fonts, you're doing pretty well. Most designers I know have about 10 times that number, although most, like me, only use a small handful on a regular basis and keep the others for occasional use in display work.
There's nothing in Photoshop currently that allows you to build a "favorite fonts" list. When Photoshop opens, it asks the OS for the fonts it has to work with, then looks in an additional Adobe-specific font directory if that's present. So the problem is at the OS level, really.
I would suggest you get TypeDNA, which I helped beta test a while back. It is a unique and quite brilliant font manager that has great tools to help you pick fonts for a particular project or find fonts that harmonize with one another (for headlines vs. body copy, for example). And it's very inexpensive. While you're at the TypeDNA website be sure to check out the FontShaker page. This is an entirely unique (and fun) look at your fonts.
