And the other one is way too expensive (for my needs and budget). For that price I could almost replace all four of my internal drives with 2 6TB drives.
Were you looking at the model that is $150? Make sure the "color" is set to TS431U. There are many devices under the same listing and the way Amazon does URLs I don't know how to provide a direct link to the exact model. For me if I go to the link it shows the TS431U by default.
