Great starting place for someone who knows CO2 lasers. I have finessed a similar chassis for 8-9 years and it has served me well. A 130w tube will be more than that tho.
If you follow the link its $400 if you willing to wait on it from there China warehouse. It it a pretty incredible machine. If no one wants it i may just fix it and keep it, but i really dont need it!
Important- ask if the tube has been checked for power and beam shape by whoever you are giving your money to. I have used LightObject in Calif for years and never been burned. Gene
