	I just purchased a floor jack from Sears. It seems to be
	made very well. There is a sale on this jack and a pair of
	stands for 99.99. I haven't used it yet but I don't think
	I will have any problems. The jack has a safety valve for
	both overloading the jack and over extending the piston.
	Raising and lowering the jack is done by rotating the handle
	either clockwise or counter clockwise. The mechanism is 
	done through a set of gears rather than some type of 
	universal joint. I thought this was a good idea.
	In the end ,however, I think you will find that you
	get what you pay for and when I am working under a car
	I don't want to find out that the $30 jack just failed.
	Oh, by the way, the jack is constructed from cast metal
	right down to all four wheels, not some nylon or plastic.
	It also has ball bearings in the pivot wheels and about
	a 5 inch cup.
