I'm considering 2 Fire models for my first device. The sellers give this information:

amazon kindle fire hd 3rd gen ereader tablet for $30
amazon kindle fire hdx (3rd gen) 16gb, wi-fi, 7in for $43

I'm confused about the difference between these, both are described as 3rd gen. Any thoughts on which to purchase? I plan to use Calibre to manage ebooks when I get started.

Note, when I registered I listed device as Kobo Aura One. This is the new device I think I want, but I'd like to start with a less expensive device first.
