[Swansea Hackspace] 40W CO2 Laser

[Justin Mitchell]

You did however correctly identify the type of tube we would need to buy
at regular intervals when they burn out, cheap ones claim a life of 1000
hours, but can often be much less.

£110 is roughly the bottom end of the market from what i've seen,
although i was pushing for the 50W version for our starter machine
