I do color printing at home both from negatives and slides.  From slides
is a little easier because you can see directly with filter colors
you need to add to shift twoards the color that you want in the final
print.  Processing time is somewhat longer because you go thru
3 chemical baths rather than two.  Also the color reversal material
is more expensive.  I have used the old Cibrachome and was happy
with it.

Basically you need an enlarger that will accept color filters
or a color head.  I have both, however I use the filters, because
the light level with the color head is not uniform.  Also, you will
find that once you find a particulr filter set for the paper you
are currently using, most of your prints will be OK
particularly if taken with an automatic exposesure cammera and
similar light conditions.  You will need a drum to process and
a drum roller is you do not want to roll the drum manually.
A timer for the enlarger is helpful.  An exposure meter is also helpful
and an accurate thermometer.  With the drums I can make a print
every 30 minutes.  With Ekaflex, I expect you could make one every
10 minutes if you want to see the result before making the next one.
I bought my equipment before the Etaflex was available.  The choice
of paper size is limited, however I think the ease far outweighs
the limit of paper and choice.  Only one chemical is required and
it has long life.  I understand at least a year.  For the drum
process some of the developers have a mixed shelf life of 3 to
40 days.
