I spent a long time looking at affordable lifting solutions and concluded there weren't any. Besides, I'd rather spend the ?1.5k or so on the car.
So, I have a pair of stout 4x4 hardwood beams running front to back on either side of the car under the sills, sitting on axle stands, set in place with a trolley jack. Gives enough room to roll a creeper under the car and access the bits I need to get to. Obviously not as fast as one of these jacking solutions, but sure is cheaper. To get the car up, I first drive it onto a pair of ramps, then fit a beam and jack from the rear. Once at the maximum height the stand is put into place. Repeat for the front (lifts the front wheel off the ramp), go to the other side and repeat. Remove ramps, get to work. I was surprised that it takes only 10 minutes to do this, and it made a real difference to working under the car vs. the drive-on ramps alone.
Kind of like this fellow who documents his sill replacement here:

Picture on one of my other threads:
