I have the smaller version from Lesco. It has a 1/2 hp motor on it. It works good for what I use it for, but my blades never get that bad. I run a real sharp blade bevel angle, so I am grinding alot of steel. I usually change this blade bevel and grind the bevel longer (about to the center of the blade) using a 4" sidegrinder first (initially). The only problem with the Neary, was that the bed is too small, and I would get a little bit of wobble out of the blade toward the end if I didn't hold it just right. I bolted a piece of 1/4' flat stock on it (about 10" x 3 or 4") with countersunk allen screws, and it works great - smooth all the way through.
