Space Flight Trading Game

[Warhammer]

Can anyone recommend a good space trading game?

Space Rangers Series (http://store.steampowered.com/sub/3092/) (This is actually a combo game. It contains turn based space combat/movement, text based missions and real-time strategy combat all in one game. My favorite one so far).
X Superbox (http://store.steampowered.com/sub/6330) (Just got this game a few months ago and I am only on the first one. Good series, active community.)
