I've been looking into the fiber laser arena and I see lasers that have a cabinet and some that they call portable, I am trying to figure out the pro's and con's of the 2 and if I were to decide to purchase one which would be the best way to go? I saw a portable that is 50 watts by Ray Fine that got my attention, is it a decent machine? are the portables really that portable? or is there some other machines that might be better? Just looking for opinions.......Thanks Terry Wade
