Similar to Pingu, I have amassed a varied selection of trolly jacks. Heavy-duty high lift for commercials, lightweight and small for carrying in the boot. I even have one of the tilting lifts that I have never used as it is too much hassle to put together. They all have their uses, however, I have a gravel driveway which makes moving the jacks around a really hard job.
I now have a 3 bag air jack , it doesn't need an overly large compressor.

It is light enough to carry around and after connecting an airline from a full compressor takes about 10 seconds to lift the car. I was going to buy a second one but it is so quick to use that I just use an axle stand, press the button to lower and reposition. Takes 5 minutes to lift all four corners up onto axle stands.
You can get 2 or 3 bag jacks, the 2 bag jacks have a lower profile and the 3 bags a higher lift. If you have a solid base you can get the jacks with wheels and a long handle to position them.
3 years ago one of these jacks would have been £500+ now you can get them online for less than £80, even if you have to buy a small compressor they are great value.
I almost never use my trolly jacks anymore.
