I am considering building aeroponic system. I did some small preliminary research and I only pump model I saw recommended is Aquatec 8800. Nobody sells it in my country, I saw them on [directnine.eu](https://directnine.eu) and [amazon.co.uk](https://amazon.co.uk) but I wonder if there are other pump manufacturers that are high quality and more avaliable here in EU.
Also,I checked the Aquatec website and they have multiple pump models like 7800, 6800, 5800 and 550. Why is everybody only talking about the 8800, what is wrong with the other ones?
