I have one. I wrote a review a while back. Still going strong. Cut a bunch of steel for a snow plow rebuild I did just a week ago. And I can fold it up, carry it around my garage, and put it on a shelf until I need it again.
It uses TCT blades - often called dry cut. The key to all dry cut saws is keeping the blade speed low enough. The gearing puts the blade speed on this saw around 2000rpm as compared to something like 3800 for a wood saw.
Cuts like a gem, but keep in mind that the anti-kick back blade is necessary for really thin stuff or it will snag your work and FSU. The steel specific blades work great for heavier metal, are cheap ($40) and last quite a while.
It's a cheap saw. Harbor freight quality base and glides, but I've cut a lot of steel with mine and for the price it kicks ass. I'd LOVE for someone to build the same thing in a $800 version that has 4 times the quality. The idea is excellent. The application is what you expect for $200.
That said, it cuts a hell of a big piece of steel for $200. I don't know of any other saw that will cut a 4x12 steel beam in a single pass for anywhere near that price.
Edit: FWIW they sell this saw for $399 at the local tool distributor. I paid $250 online. Sears sells it for $610. (Or should I say Sears doesn't sell any?)
