I bought one of these ( HEAVY DUTY 3 TON HYDRAULIC CAR 4X4 GARAGE WORKSHOP MECHANIC TWIN PUMP JACK STAND | eBay) to do the DMF/clutch change on my Passat, I was very impressed, it has many cast iron parts including the 50mm wide wheels and the rest is 7mm plate, it weighs in at 40Kg and will lift a 3 Tonne load from 145mm to 520mm and with its twin pistons it does this quickly.
I think it is a bargain at £80 delivered, it saved me time by lifting the front of the car high enough to remove the transmission with only one lift.
