I recently purchased a motorcycle lift table based on a recommendation from someone here and it has been one of the best additions to my shop. Mine is an air lift, its fast and there will never be any oil leaks to deal with. The primary table is 2 foot by 7 foot and it has extensions to make the table size 4 foot by 7 foot. I recently finished two 4 by 8 foot signs and it would have been more difficult without the new air lift table.
I have four of the smaller Harbor Freight hydraulic tables and they have been worth their weight using them for large sign projects where I have to move hundreds of sign plaques around from machine to machine.
