Tip Of The Day: View .EPS files in Quick Look
You may have noticed that .eps files do not work in Leopard's Quick Look -- only the icon with some file attributes is shown.If you want to get a thumbnail icon and a preview in Quick Look, you may want to download the free EPSQuickLookPlugin and install it into your ~/Library/QuickLook folder (if there's no such folder, just create it). A restart may be necessary.

I just found a pretty handy plug in for OSX Quick Look to preview .EPS files.
Its always worth a look for an external plug in if you have a filetype which is not supported by osx.
Have a look here. Maybe you find something useful.
