Well, I took the plunge and picked one of the Princess Auto lifts up yesterday. I'd buy a table, but a) don't have the room for one and b) would still need a jack to be able to remove wheels.
The lift isn't quite as described however - it doesn't have two 'fingers' to go under the bike - it has a square platform that lifts the bike - rectangular tubing welded together in a square with rubber padding on top. The hole in the middle 'should' allow for oil changes.
The rest is similar - wide spread legs on the base - will be able to put oil drain pans below etc. I did notice on the model they had in the store that the platform tilts slightly back towards the jack body as it rises. So the bike wouldn't be perfectly level when raised. Not that far off level, but still an annoyance.
I haven't opened the box yet - still contemplating it. I think I'd have opted for the more typical jack they used to sell that is like the Crappy Tire version. It has adjustable fingers that you can cradle the frame with, allowing for exhaust etc. to be worked around. But, it doesn't leave the bike open underneath for oil changes. Pretty minor issue though. Also about 1/2 the price of this one. Alas they don't seem to sell it any more.
Will report in when/if I assemble this one.
