Its very easy to downgrade monospaced fonts by labeling them as simplistic and uninteresting, but they are more than that. A very great example is the kontanter free font. It is an experimental monospaced font loosely based on Gotham bold. Kontanter feature a lot of languages to support a lot of European languages with alternate letters in lower case.
Thanks to Font Fabric for this awesome font. Check out his portfolio for more amazing fonts, free and premium.
