I probably had 50-60 originally, but since then have added maybe a thousand or so. Sometimes I wish I had not. Easy to make a choice when you are limited (and everyone has their favorites), but I spent an hour one nite trying to find the right font...frustrating sometimes.
You might look at this "Font Viewer." I use it all the time. Got my Windows font file and font 2 files for purchased upgrades. This little program makes managing fonts very smooth.
That is AWESOME! I wish I could get that hour back I wasted...I really needed it. 25 bucks is reasonable for a lifetime of downloads. Advance Font Viewer is pretty trick!
BTW, there are some other great (and free) utilities on that site including WinOff (which I use alot with Vegas). It will monitor your CPU and shut down the machine when it falls below a preset useage. Great for long renders. When the render is complete the machine shuts down. You can also get a screen shot before the shut down to verifiy the render. Many other options.
