I've had a Cobra Trackside 110V unit, a Hudy (not fully auto) and the auto Integy one. I liked the Hudy, but it wasnt' fully auto, and the Integy one, I only complaint I have is that the blade adjuster backs off if try to cut too much. Other than that, I like the Integy. I've had mine a year and I found that Tile Cuting blades with the tunsten carbide edge works great for a very clean finnish, but I you just get regular "laser" cut hack-saw blades, it provides a very nice finnish, though you have to replace the blade after about 10 sets of tires (40) I cut my own hack-saw blades down for the Integy truer and for the 25 you get from one hack-saw blade, it is cheap enough to keep me very happy. A budy of mine has the Hudy and together, the Integy was only a minute slower for a set of 4. I can live with that.
