I feel that Linux From Scratch is the next step to take in learning linux for me.

However, I can't stand reading e-books off the internet. I like to have a book to hold and a nice relaxing couch to sit on.

Normally I would print it out, but seeing as LFS is 200+ pages I thought it would be better to just buy the thing.

So I guess I would buy it from cheapbytes. Are they a reputable dealer? Will I never hear from them again once I send the money?

And most importantly. Is getting the LFS 6.0 book a waste because it'll be outdated in a couple months?

If cheapbytes ripped off the customer, I doubt the guys at LFS would continue to provide a link on the LFS website.

The current stable version of LFS is 6.2. You'll have to decide if 6.0 is outdated. Look at the package versions used in 6.0 and decide.
