I've worked with Adult eBook Shop.com to make Freedom is Slavery available as a relatively lightweight eBook version for the low price of £3.99 (roughly $6 US).
This is less expensive than the version available at Lulu. One strange thing about Lulu is that the PDF used for print is the same PDF used for their download, meaning that it needs to be a lot heavier with the 300dpi images. The version available via Adult eBook Shop.com is saved specifically for a faster download. The images are still there, and still beautiful, though they're saved at screen resolution rather than print.
Now... go buy a copy!
