Mine or the $80 sunex ones and I only have 2 of them, he has 4 of them and I think they are OTC? mine has a simple round base about 8"s wide and pins together, his has a 4 post base, fits together mmuch better, and has a foot pedal, just a much better unit..
His look like this except have a foot pedal too
http://www.amazon.com/dp/B000XSJK7S/?tag=atomicindus08-20 I still like mine because they are easy to store, light and easy to move around, BUT no doubt his are more stable...
With his stands I seen him lift a dc tudra up set the 4 stands and drop the lift to the floor, I also seen him {well i arrived after it was done but seen it sitting there} drop the cradle out of a caddy and the car was still in the air with the 4 stands under it, he does everything with that 4 post, motors, trannies, rear ends, he actually did the gas tank in utility body with it last year..
BUT I do love my 2 post clear floor lift, granted everyone can't fit them or doesnt like them, but I am so used to using them, its just second nature...
