Hi,

I have a budget of ~20.000$ and I would like to buy a system to record and stimulate (electrical micro-stimulation) from laminar electrode (i.e. Plexon U-probe http://www.plexon.com/products/plexon-u-probe). I am working with behaving macaques. At the moment I am not interested in a perfect single-neuron spike-shape isolation. 

I would be very grateful if you could suggest me any item/company.

Thank you!
