It is curious to note that CAFTA is the subject of much debate here in the states too. Except that Congress thinks its a bad deal for US farmers, grower's and the like.
I admit that I am just becoming educated on the subject and am willing to be educated, but there are clearly two sides to the story.
In any event, one nice thing would be the elimination of most of the duties on consumer goods to the member nations. Given the cost of some things are nearly doubled by the duties, I'd think that would be an incentive to investment and trade.
That said, this is an early opinion and one I am open to revisiting.
