One thing they don't like to talk about is that after the carts are 
about 1/2 empty the amount of ink flow changes, making delicate color 
management impossible.  Constant ink systems or systems like the 3000, 
which don't use the above head cartridge system might be better.

Now, come on... are you telling me wet color prints come out looking 
color balanced?  Some papers look very blue until they dry, Ciba looks 
magenta brown.  At least they did when I used to do color darkroom work.

Tell your models to get a tan or eat more carrots! See my response to #1 
regarding greens.

I think you just did ;-)

Approaching perfection is always costly.  What does a really good 
enlarger and lens cost?  What does temperature and time controlled 
darkroom equipment set you back?

You're either too hard on yourself, or the printer, or both.  I'm not 
trying to be unkind here, but if you cannot afford the tools necessary 
to make the result you are after, either go back to an earlier method 
that works (chemical) or accept the flaws and recognize that 99% of the 
people looking at it will not see it the way you do.  Only you have the 
internal vision of what your expectations are, and although I'm not 
suggesting you toss those goals away, you need to recognize the 
limitations of the tools you have to work with now, and that you will 
improve them as they become more affordable to you.

I sold many people on PCD when film scanners and CD-R burners were 
either vastly expensive or totally unreliable.  Now, I recommend they do 
it themselves if possible.  The market changed.  If the Noritsu/Fuji 
silver paper machines can get you where you want to be, it make be 
cheaper than a $7500 5000 with RIP, and it is certainly cheaper than 5 
years of therapy ;-).

None will fulfill your needs in the price range you are looking at right 
now, at least with current technologies.
