Want to buy used zAmp only (no system)

I am interested in purchasing just the zAmp plus sensors and cord from a Neuroptimal V2/V3 system. I am hoping maybe someone has a broken unit or other situation in which they can’t sell the entire system and the zAmp is currently going to waste.

Please feel free to email me at jkhereford@gmail.com if you have one you may be able to sell.
