im sure there are many many threads of this nature, but hey im going to start a new one ;)

I know nothing about plasma cutting, not something ive ever needed. but I need to cut 3mm aluminium sheet fast and accurately. im not after big an bulky, im after small A3 cutting size and powerful.

im almost tempted to buy a denford microrouter and mod it.

what would I need to cut 3mm aluminium fast and what sort of finish should I expect?
