I have used a Coffing brand, which is expensive, and I bought a cheap Harbor Freight one. I have had no trouble with either one.
Simonsrplant, I thought the same thing until I used one. They are handy as a shirt pocket because of how small they are. There are many components that weigh less than 500 lbs that are awkward to handle, even with a helper. think starters, pumps, driveshafts, differentials, etc. I have used a ratchet strap for these, but you have much more length of lift.
