Ballards has moved and changed
I don't know if Geoff has anything to do with the business any more.
I was unable to get any Ballards specific products last week.
I loved the old Ballards
and dont feel the same any more
I have one I bought from a friend when he sold his big something 109 - Suzuki maybe -I think it weighted 250 kg or probably more. It doesn't lift as high as you ask though, I think about 40 - 50 cm. It is quite compact, I store mine under a bench or on its end against the wall. It has rollers, my friend used it like a train turntable. I think you can get them from Autobarn/ Repco type places and maybe a couple 100 $, but regularly on special.
Although it doesn't lift a long way I've used it to raise bikes for working on them and also for lowering engines for removal. It's been good especially in combo with a short stool.
