New Acme or similar--recommendations?

Looking to get recommendations/suggestions for a possible
new machine and possible options (such as bar feed, etc).

Supplier has a smaller (up to 1.25" bar stock) older Acme,
and the idea is to be able to make the vast majority of
parts on a new machine--but keep using the older one for the
smaller sizes if it is cost-effective--and to be able to run
large and small sizes simultaneously if needed.

Parts to be made are from round or hex stock, size ranging
from 9/16" hex up to 2.25" hex (across the flats). Part
length ranges from about 5/8" up to about 3".

Materials to be machined: aluminum (75%), low-carbon steel
(20%), and stainless steel (5%).

I have already looked at the B&K web site for Acme, and have
requested a quote with potential options.

They are not the only supplier of this type of equipment.
So, I am looking to get info and recommendations (buy or
avoid--and why) regarding other machines and manufacturers.

Meeting with the money-boys (not acct dept) in less than six
weeks, so the reason for asking is pretty simple. I want to
be able to tell them which are the most reasonable choices,
and why.
