Ok so I am way late to this discussion but for those interested in Lasers another option "may" be for you to build your own. This guy has Plans at https://www.furtherfabrication.com/
He is a set designer on major motion pictures and after working with many lasers in the industry decided to build his own. I actually own one that i bought off of a member in a facebook group. Works great , has a 90 watt tube. Usually when guys sell these they are moving and dont want the hassle of moving them which means you can usually buy at a good to great price and the work is already done. Anyway thought i would share. Also here is the Facebook group: https://www.facebook.com/groups/FurtherLaser
