<br>
Has anyone bought a laser cutter in the last three years ?<br>
<br>
A couple of people from this group are toying with the idea of buying one capable of cutting 4.5mm Perspex, or MDF; hopefully a desktop unit.<br>
<br>
Experiences, good and band, manufacturers, cost, general observations appreciated.<br>
<br>
Thanks, Mark<br>
