Suggestions for a combination of fonts to be used in a math thesis

Forums: 

Greeting font anthusiasts,

I have recently finished typing up my Ph.D. thesis in math and I am looking to improve its overall appearance. Let me say right off the bat that the standard font that tex uses, i.e. Knuth's computer modern, is not bad; I'd simply like to explore some further options. I am using the KOMA script latex package which sets chapter and section headings in sans of whatever font family is used for the main text. While this can be changed, i.e. need not be sans of anything, I think I'd like to keep this feature and thus use a serif typeface for the main body and a sans typeface for section and chapter headings.
