I didn't buy one yet (have my good ol' Eheim AC pump), but when researching it seemed pretty clear to me that the best overall DC pump in terms of features, reliability and cost are the Reef Octopus Varios series. They are quiet, reliable, controllable, apex-ready and come with all the adapters you'd need, and even a float valve to create an emergency shut off. They seem like a no-brainer to me. In fact, unless you use Reeflink, I don't really see any reason why someone would buy a Vectra for $100 - $200 more. The Waveline pumps aren't as quiet, and the Jebao are questionable in terms of reliability. Of course Abyzz or Red Dragon are the cream of the crop, but are they worth a $1,000 premium? The answer is unequivocally, no.
