Reddit mentions of Wonder Woman: Down to Earth

First let me say this: While a lot of the Rucka trades are technically out of print, you can still find a lot of them hovering at or near cover price. But the trades were still orderable through Diamond comics until very recently, so a lot of comic shops still have these books in stock. I can't remember the last time I went into a comic shop that didn't have at least a couple of Rucka's Wonder Woman books.

Read order:

• Greg started his run with an OGN titled The Hiketeia, available in both hardcover and paperback. While not directly related to Rucka's run, it does set the tone.
  
  After that, he took over the main Wonder Woman (volume 02) series at issue 195, and remained on it until it ended at issue 226.
  
  From my post on /r/WonderWoman:
  
  
• Down to Earth - Collects issues 195-200. Artist: Drew Johnson (195-200), additional artists on issue 200.
  
  
• Bitter Rivals - Collects issues 201-205. Artists: Shane Davis (201), Steve Sadowski (202), Drew Johnson (203-205).
  
  
• Eyes of the Gorgon - Collects issues 206-213. Artists: Drew Johnson (206-210), Sean Phillips (211), James Raiz (212-213).
  
  
• Land of the Dead - Collects issues 214-217 and The Flash 219. The Flash 219 written by Geoff Johns with art by Justiniano. Artists on Wonder Woman: Drew Johnson (214), Rags Morales (215-217). The Flash 219 and Wonder Woman 214 were also both reprinted in Prelude to Infinite Crisis.
  
  
• Mission's End - Collects issues 218-226, the end of the series. Artists: Ron Randall (218), David Lopez (220), Rags Morales and Cliff Richards (221, 223), Cliff Richards (222, 224-226). Artists on issue 219: Tom Derenick, Georges Jeanty, Karl Kerschl, David López, and Rags Morales.
  
  This final trade collects just the Wonder Woman issue of the Superman: Sacrifice story arc (collected completely in the Superman: Sacrifice trade). The Wonder Woman trade does feature a nice, detailed synopsis of what occurred in the various issues of Sacrifice leading up to Wonder Woman 219.
  
  If you're looking for single issues, you should have no problem finding any of them, except for maybe first-prints of issues 219 and 220. But even those first prints shouldn't run you more than $4-$8 if your store isn't ripping you off.

A lot of issues are also on comixology, beginning at #201.
