Booster Fans

I'm wondering how they work for an intake fan? Should I run 2 of these booster fans? Instead of 1 solid inline? The 2 booster fans I have been looking at, either brand better then the other? Im leaning toward the Suncourt just because I will prolly get it quicker.

I have a 3.5x 3.5x 6.5 ft tent, and I use a 4" like that suncort for an intake, works fine.. however that price is twice what I paid at htg supply for the same thing.
