I'm looking on ebay to buy my first Co2 Laser Engraver and I've found that there are several versions or revisions of the same machine:
SH K40IV
DC K40III
and parallel and usb version
....
I understand that there are 4 generations ... many shops that sell on ebay is the third but I found a site that sells the IV
Does anyone know the differences?
TKS!
