I just knocked out (what I think) are the perfect settings for ebook pdf technical books that are heavy on diagrams & text. I played around with a bunch of everything and went over them A/B tested on the Kindle 2 itself for the past 2 hours. > )

My recommended settings:

400dpi (best result on kindle display itself):

600dpi:

1600dpi (text is too wispy and light hard to notice bold):

I felt that unpaper wasn't necessary because these pages weren't scanned, and it only hurt the quality of the text. On my PoS work laptop, a 600-page technical manual was converted in about 40 minutes with a final size of ~65mB making it about 10mB for every 100 pages. Not bad at all for graphics/diagram/table-rich technical documents, and a HELL of a lot better than Amazon's auto-service (when I submitted the 600page monster I never got a response back, and single-pages came back horribly misformatted without any images at all (basically plaintext stripped with wrong symbols and characters everywhere).
