I've got a Super B (and four other Stars) and find it a very nice gun. I wanted one 1911ish 9 and after looking at the choices and reading as much as I could find, I went with the Super B....which got me interested in the 28 and I bought one, but then I had to get a 30MI (all steel) as the next in the series and then the 30PK for an alloy frame and finally a Star UltraStar as it was their last pistol design and first poly pistol...and bingo, I'm "collecting" Stars.
I echo what others have said: sights are "adequate," trigger very good, handles just like my 1911s but nothing interchanges, and get the Super B as it didn't visit Russia and takedown is a snap.
Good luck and good shooting.
