Quick Look can do EPS too.

Have to find the correct version of that logo to add to flash, but don’t want to load them all in the unbelievably slow preview app, or bother loading up Illustrator only to find out the designer sent you a photoshop eps without vector data? Sorry I’m venting a bit, but this plugin really saves me time—and it’s free.

There’s actually a whole bunch of other plugins that are helpful too (beware: the zip one is pretty slow though).
