The aluminum one from Harbor Freight sometimes is on sale for $99. It is lighter that the steel ones, but I wouldn't trust any of them to hold the bike for long with only the hydraulics. Use the locking device. Oh, bty the lock on this one is not (I wish it was) height adjustable. You pump the lift almost as high as it will go, insert the included steel rod through the lift frame and them slowly release the valve to allow the lift frame to settle on the jack frame. I like it and others. Any lift is better than no lift.
