Lots of choices, and most do what they are built to do. I've used many of them:
1. Tunze - the endurance champ. Almost indestructible and plenty of flow. Essentially silent.
2. Vortech - currently my favored flow pumps. A little trickier to use, but enduring if you do so correctly. External motor means some noise.
3. Apex WAV - a little temperamental, with a tendency to short out. Awesome flow though, integrated with their controller, and essentially silent (though vibration in the cords can buzz).
4. Sicce voyager - pretty basic flow pump, though reliable and silent
5. Jebao - mixed. Inferior, 'budget' quality. Flow is good and they are silent but not particularly long lived.
I've not used any of the gyre pumps.
