If you do end up going with the FSA crank just make sure you get the later model (the one that someone poster earlier) where the whole spider is carbon, the earlier models had some issues with the crankset loosening up and giving people problems.
But, again, as other people have said, there are better options then the FSA although the FSA isn't a terrible crankset. For example it comes stock on the Sonik. Which isnt the best bike you can buy but its also far from the worst/entry level.
I think the failure that someone was reffering to was in refernce to the older model cranks, as far as i know the newer cranksets dont have this problem. So if you do want to get carbon cranks the FSA isnt a terrible choice, as long as you stay away from the ones that people are known to have trouble with.
