I have a Sealy 1025HL as in some of the above posts and a Sealey 1153CX. Both are robust pieces of kit and more than aedquate for our cars, although the former is a little more useful due to the extra lift.
The 1025HL came 3rd in the Autoexpress 2012 jack tests.

I do howver fancy the CJ Auto's adjustable ramps and have been thinking about getting some for a while.
