In fact I used a combo old scissor jack and low profile hydraulic jack until I recently bought the other low profile hydraulic jack when it was on sale. I liked the idea that I did not have to be sure the jack rolled under the car to keep the proper alignment of the jack saddle with with the jack pad/puck.
Scissor Jack is inexpensive and less concern about maintaining alignment with jack pad/puck than with Hydraulic Jack..
