Hi,
In reply to your request for a good IHS  automated stainer.I have a suggetion.
The immuno stainer made by BIOGENEX  known as OPTIMAX  is very good I  am 
using one for the past year and a half and it is giving good results.The best 
thing about it is it has a duel syatem you can use it with bar coding or the 
open system. it is very flexible  and you  can tell it what to do, instead of 
 it telling you.

akbar.  good luck
