Hi All,

   My own equipment, an ancient Clausing 12x36 lathe and a 
"benchtop" Taiwanese Mill-drill, take up 2.5'x5' and 3'x4' of 
floorspace, respectively - literally 9' linear feet of wall 
space. The mill's travel is a little too short to mill and 3 
cyl. head in a single pass.  I've had to do two set-ups for 
that particular job.  If I'd ordered the next size table (an 
extra $100, then) I'd not had that problem.

   Take a look at these two, they're fairly typical of what's 
available in the way of reasonable-quality imported tools.

   Total investment: $2600.00, and I'll guarentee they'll do 
more than any currently available 3-in-one up to $4000 will do, 
and occupy only four more feet of your wall.

   Some others:

This one is a little more versatile, in some ways, than the 
Southern Tool mill above.  But it does have a rather short 
quill stroke for drilling.  If you already have a drill press, 
that's not a worry.  The table size is about the minimum for 
serious work - other than "miniature".

   By the way, don't get fooled by claims on some of the 
small lathes, often advertized as "tool room" lathes.  The 
small units are incapable of holding tolerances necessary for 
true "tool room" use.  As someone else said (Mike?), .002 is 
often the best they can do.

   If I were buying my first Mill - and limited to less than 
$2000 - this is what I would buy today.  No belts to move when 
I need to change spindle speeds; table travel is big enough for 
an intake manifold plate; the head can be tilted up to 45 degrees.
In fact, if I can find a buyer for my old one, I may just get 
it anyway - even though my "next machine" budget is being 
built up for a Bridgeport type machine.

Another (relatively) inexpensive production-size lathe (<$1000.00)
The Jet above is probably a better machine.  I can guarantee that 
this one is made in China (as in: The People's Republic of ...)  For 
that reason, *I* wouldn't buy it.

   Also, don't snuffle at used equipment.  Machine tools made 
back in the 30's, 40's and 50's were made to outlast several 
Tool-and-die Maker's lifetimes.  Get one that has been 
reconditioned by a good shop, care for it properly, and you can 
hand it down to your grandchildren, still capable of the same 
fine work it did the day it was installed new.

Dale R.
