Lets talk floor jacks.
Man, if you work on your car a lot, buy a decent jack.
I used a Craftsman about like you're looking at when I got started. Used a buddy's Matco one time and had to have one. Pad rests lower, raises higher, is bigger. Jack goes higher on a single pump, wheels around the garage easier, has a rubber pad on the handle to protect the bodywork.
This is the one I bought ten years ago. Constant use, it still works like new.

EDIT: I guess the price there is just for the Ram. I bought mine off the tool truck for $150.00 on sale.
Twice as much money, 10 times as good.
