I think 128 or 256 channels is necessary. The Bio Semi, Brain Products and Geodesic systems looks good, what are you advices please ?
Check if this paper gives you help:

Thank you Béatrice, I am currently working for the research project of Anne Beuter and Vitaly Volpert.
I would like to have feedback about EEG devices used by other researchers in order to make the right choice to continue the research on this topic.
I have found different EEGs from Neuroscan, Bio semi, Geodesics and Brain Products, but I only have experience with Biosemi.
We used a 128-ch EGI system for studying traveling waves in sleep, results were very robust:

Perfect ! After some research it seemed to me that this was indeed the right system.
Your researches look very interesting by the way.
