From riding three of the four bikes you mentioned, here are my opinions:

Pista -- my brother owns one. the chrome looks the cleanest of the choices, super lightweight, great bike, responsive. super smooth with sugino cranks.
Kilo TT -- i own one. very good value, perhaps the frameset even moreso than the complete. the angles are in between the Pista and the Steamroller, and feel pretty good. i replaced the stock wheelset and other parts on mine, but with just a frameset, you won't have to deal with low-end stuff.
Surly Steamroller -- my cousin owns 2. a bit more roadish geo, but feels great and sturdy. when we went to the beach, he put on slightly larger tires and it was a lot of fun.
