What do you want the pump for, as a rule there isn't a need for an air pump or powerhead when you have a good filter like the one you bought, If you want the bubble look, there certainly isn't anything wrong with it, but it isn't necessary for the fish.
Rena is the one i see reccomended most, I don't use air pumps in any of my tanks.
If you are intending to set up a ugf or RFUG, then i wight suggest a penguin powerhead set-up in reverse, much better than conventional, and perfectly silent.
