Right now I'm digging Skolar + Brandon Text. :)

The possibilities are endless. But choosing a typeface works well with versions "sans", "condensed", "serif" and "Slab" to really harmonious compositions.
I found this page to be so so helpful here:
...very high quality as normal from 'Smashing Magazine'. I applied the theory to some more wordy products that I made and the results just looked so fine. IMO this is the very highest one can go in typeface work... once one gets it right, the amount of 'polish' it adds to a project is just massive.
I like using United and Farnham with some Soho, too.
Sometimes sticking with the same font author works... you can feel the family feeling!

A great site with a lot of combinations, and identify s the fonts used.
I've recently purchased "A Pocket Guide to Combining Typefaces [Kindle Edition]
by Tim Brown". It is a great resource. I highly recommend it.
You can mix sans serif types with serif- or Hybride- types. Or light with bold ones. Script and serif/sans serif will always work.
