beam expander

[cheech226]

i bought a 10x melles griot adjustable beam expander a few months ago and was amazed to see it in action. i never was able to find an adapter to connect is to any of my lasers and had to just use tripods etc. to hold all in place. altho this isn't bs&t, i thought a post in this area my get some views.
i'd like to sell it. please pm me if interested.
