QTR-Quadtone RIP

You can pretty well pick any price you like from a few dollars up to
$1100 or $1200. All you really need is something that is calibratable
and will read visual density accurately. A few months ago I saw a
tetherable Cosar CMYK densi with standards, fully functional, sell for
 $16.00 on E'bay. It will work. I know. I have one I purchased in 1997
for about $1000 and used it recently for this. You can also get the
Colorvision Printfix Pro package with spectro-colorimeter for about
$400 or so and do this as well as make your own color icc profiles
with it. Beyond that, you could go for more expensive packages from
X-rite or go the i'1 route. You also have options for automated strip
reading densitometers used on E'bay at about $200 or so, less if
you're lucky. I work from two widely separated locations and, at one
of them, use an efi mousitometer type densitometer I gave $5.00 for.(
I had to write software to read and calibrate it however, so it
probably was expensive if my time were valuable these days.)
