I have just purchased an Argon Laser head + PSU off of Ebay and after the auction had ended the chap I purchased it from got in touch with me. It's slightly edited as to remove the chat between me and him but you should get the drift. He sounds a genuine chap, proof will be in the pudding when it arrives but on the whole, if there is anyone out there that wants a 'tinker' with a cheap old Gas Laser or two then here maybe is your chance?

I am about to list another argon laser on EBay, we have a surplus of these of which have different ages, some 4-5000 hours old, and some over the 10,000 mark, i was wondering if you was interested in purchasing more of these ?
These lasers come from decommissioned industrial equipment which had multiline filters with them (I'm selling these separately) and we do get these lasers from time to time. i have some older unit which are or have passed the 10,000 hour mark (this is the maximum the counter goes up to so i don't know how old they truly are). I was thinking of selling these cheap to people who know about these lasers, so they could tinker with it (at there own risk)
kind regards
Jason.
