Produce the CD. Produce the printed manual. Produce the website
download. You want to calculate the cost of the stuff you recommend? More
than the cost of producing the print manual to start with.

My suggestion would be to do away with the printed manual, like everyone
else seems to be doing.

Send a quick start piece of paper, like the others, with links to where they
could find documentation online, using perhaps some of the suggestions
others have put here.

You can probably do that for free, with minimal one time investment of your
time. Put it all in PFD, and that can be the exact same file you put on a
disk to send with your product, so the non internet people can find your
manual to print, if and when they need to.

Don't sweat it, above all. If the print is killing your bottom line, then
your choice is made, IMHO. Do away with it.
