Looking for FF Seria Pro family as well:
FF Seria Pro: [URL="http://www.myfonts.com/fonts/fontfont/seria/"]http://www.myfonts.com/fonts/fontfont/seria/[/URL]
FF Seria Sans Pro: [URL="http://www.myfonts.com/fonts/fontfont/seria-sans/"]http://www.myfonts.com/fonts/fontfont/seria-sans/[/URL]
Please note that I do only and particularly look for the PRO version of the family, not for homemade-from-Type1-converted craps. So, please don't bother if you don't even now what the PRO in type-context means and if you don't have original PRO versions. Thanks for your understanding!
