You might want to look up the max thickness and other common issues hobbyist level laser welders have before purchasing, or at a minimum wait for the laser welders to mature a bit more. You'll spend less than half and be far better served with a cheap tig welder at this point in time.
I’m mostly concerned about the learning curve. The laser welders I saw can be used blindfolded and offer enough penetration. I noticed a lot of negative comments but mostly from people who spent years honing their craft and feel obligated to gatekeep it a bit.
