I did some Google searching and seen several people talking about this. Looks like a $1000 bill will buy it. Allot of people with back injury's or leg amputations were excited to see this and buy it so they could get back to wrenching on vehicles. Much easier for them to get under a vehicle and back up off the ground.
Yes a hoist would be the ultimate thing to have. But unless you can find a decent one for the same price i would say this is a great alternative !
