I bought a number of ion lasers which I'm going to return to the seller as they're all damaged with snapped plasma tubes. One of the heads, however, is fitted with a Neos PCAOM and 4 channel driver (48062-2-.55 and 64040-75-.1-4CH-5M); I'm wondering what this is worth as it might be worth me hanging on to that head just for the PCAOM; I have another, working, head I can swap out if I do keep it, so it will be used.
