How about Eidetic Modern? It's serifed twin is Eidetic Neo.

Also, have you check Identifonts Similar fonts for Rotis Semi Serif?

drrp, double post.

I actually find Rotis semi-serif quite contemporary in a timeless kind of way, but that's just me... It's one of my all time favourites!

It's certainly becoming ubiquitous here -- not to the point of being tiresome (yet) but definitely noticeable.

thanks, Eidetic Modern and Neo look fine (as I can judge them on www.psyops.com) but I have to wait for the condensed versions.

ah, thanks, didn't know this function. Works much better than the similar guesses from myfonts.

sorry, I've searched and browsed all rotis-topics.

TheMix has semi-serifs, though I guess it's not quite the same feel.
