I've played around with Windows / GUI version of HTTrack quite a bit and it works magic if you're patient enough to try several combination of settings. One key trick is to "Get HTML first" and "Ignore robot.txt" (use responsibly), and then structure based on filenames, so you get /html, /jpg, /pdf folders, and just need to go to /html folders to get to specific pages easily. Pretty sure I can pull WPTavern and show you how Jeff. Let me know if you're interested, and I can PM you my findings on the settings that works. And no, I won't do anything with the mirror/copy. :-)
