I have to disagree here slightly there is not a huge difference in
pricing between ACME thredad and all thread. You end up spending a
greatdeal of money that you wouldn't otherwise spend if you just upgrade
to the ACME in the first place.

Also there are design points where even the tought of designing for the
ultimate makes the project impractical. Yes these are often home
projects but it isn't unheard of in an industrial situation.

So the reality is that the individual has to make due with what he can
justify. It does not hurt though to understand that ACME screws are
not that much out of line.
