You are correct - those are the same canister filters sold as Aquatop, SunSun, and Polar Aurora. They are offered in a 265, 375, and 525 GPH units and with or without 9V UV bulbs. Inclusion of media is another option. It pays to read the reviews off Amazon, as the SunSuns have thousands of reviews.
I have purchased 2 of the Polar Aurora (525 GPH with UV) and have been happy with them. They are relatively quiet, easy to maintain, and have cheap replacement parts (bought an impeller and UV bulbs). I would also suggest buying a food grade silicone oring grease to apply to the gaskets.
