I got the Northern Tool version a year or two ago. Posted a review here as well. I've been super happy with it. Still on the original blade, but it has taken some damage. Picked up a new blade from Amazon, but have yet to try it. No looking back at the abrasive chop saw it replaced. Still keep that around for trash cutting or something hardened, but maybe use it once a year. I liked that the vise jaws are cast iron instead of stamped steel, and the base is diecast aluminum. This is not really a cold saw, I see most use the label "dry cut saw" A true cold saw like a Scotchman runs with coolant and spins super slow, like under 100 rpm. These are carbide tipped and spin around 1000 rpm. Still almost as burr free, and very little heat in the part. The best thing has to be the lack of abrasive dust. Get one, you'll be glad you did.
Long arc, short arc, heliarc and in-the-dark!
