I do not know what your volume or time rquirements are,but the St5050 is good
for open architecture, and various reagent use, also possible ISH, the
Ventana is good , but you are obligated to use their detection system, Dako
autostainer, and Biogenix
stainer are good, time consuming set-ups and reagents from them are
competitive priced with everyone else. Hope this helps, you need to choose
based on criteria that fit your labs needs.              Dana
