Just ran across this.

Yep, I posted those a long time ago - I think in the thread WillieB did about his scissor lift......there are only a couple of things to note about them - they're spendy - almost as much as a regular 2 post lift.....and they only have a couple of pin points to set the height - they also get in the way of opening the doors just like any 2 post does, so if you're working underneath and inside, it can be a bit of a PITA - but then all lifts have their compromises. Other than that, I really like that they're portable and you can move them out of the way when you're not using them and of course that the underside of the car is completely exposed.
I think you can buy them thru Costco, if you have a membership there.
EDIT: Apparently not this year, I checked the Costco site......
EDIT 2: Home Depot carries them! $1995.00
