Ramps are cheaper than $60, BUT ! They are not considered "safe" if you are crawling under the car.
I jack the rear end up by the differential and place 2 jack stands on the rear jack points.
Then I can jack up the front on the crossmember behind the engine and place 2 more jack stands on the front jack points.
One of these days I'm gonna get one of those floor lifts when I find an extra $1600 lying around :
