I can think of 2 modern generators off of the top of my head. I know that PCGen has have modern datasets available. There are modern datasets bundled with PCGen, but you can also get modern datasets for PCGen from CMP ( http://www.codemonkeypublishing.com/xcart/customer/home.php?cat=323 )
RPGNow also has an online generator. The free version only does ordinaries, but the paid for one does all the classes that they have built in...and they're planning on adding more.
