In a clinical setting where you do well established procedures for diagnosis
and you charge the patient for the cost of the test the Ventana systems work
well, but if you are doing thousands of slides in research comparative
studies the Ventana in not practical and especially not cost effective.
True, the DAKO takes a lot longer to run, but you can do 48 slides at one
time and run them overnight while at home sleeping.  What you need in
research is affordable, consistant results.  The DAKO may take twice as
long, but even using DAKO detection it cost about 10 times less per slide
than the Ventana, for me, and when you cannot bill a patient the cost is
very important.  As for set up time, with auto programs and the DAKO label
printer, I think the DAKO is approaching comparable setup time to the
Ventana.  My opinion.

I think you should look at the NEXes, although DAKO does 48 slides, it can
take 2 to three times as long to run those slides, I've seen head to head
comparisons between the TAT and I would have to ask, why would you want to
wait twice as long to get your slides? Also with the set up times involved,
Ventana's system is so much faster and easier to set up.

I've seen people on here talking about the detection being closed and
possibly costing more, Ventana is the only company that can gaurantee slide
cost using thier reagents due to the 100ul per slide gaurantee and by using
thier optimized reagents, high quality, consistant slides is what you get
day in and day out. If cost is the most important factor in considering
autostaining systems, Ventana by far is one of the most cost effective
systems on the market. Give them a call and I am sure they will prove it to
you as they did to me.

That's why I am working for them now!
