I have an J&S and works great for me. It also gives me the ability to turn my bike around once I pull into the garage. Would of loved a table, but would of taken too much room.
Pro Cycle Droptail. there are two places to put the wheel chock, one for long bikes choppers, one for non stretched bikes and the back drops out for easy tire changes.
I have a Pitbull instead of a J&S only because the Pitbull lifts another 6 or 7 inches higher, and that's often the difference between standing and crouching. My bike was up on my Pitbull jack all winter getting a top end rebuild, and some other upgrades.
I'd have a table if I had space, though, for the added convienience and versatility.
After spending a few hours yesterday and a couple today installing a suspension link and shocks, on my bike on a jack, I will tell you that I will be getting a lift table.
My back and knees ache after stooping over removing heat shields and such.
