Below is what I learned from experience after having bought one of the cheap consumer level lift-tables. If I were doing it again, I would spend a little more money and get a better quality table more similar to the commercial ones that are used in motorcycle shops, which is what I suggest if you are willing to spend the money and have the space. You don't need the most expensive commercial model like is found in a motorcycle shop. There are many available that have similar features but are not quite as big or expensive.
The more expensive ones similar to what is used in a motorcycle shop have wider decks than the cheap consumer level lift tables. The extra width allows for easier loading and unloading because they are wide enough to use the the side-stand on the table. This makes it much easier to load and unload the motorcycle, especially a heavy one like an ST, because you can rest the motorcycle on the side-stand while getting the straps organized. This is all feasible with the narrower tables, many of us including myself do it, but it is much easier and with less risk of dropping the motorcycle if you can use the side-stand, especially if you are doing this alone.
The more expensive ones also have a drop away section at the rear to facilitate rear wheel removal. The cheaper ones usually only have a section that is removable like a trap door, but the frame stays in place and remains in the way. Some also have a drop away front section to facilitate front wheel removal as well.
The better ones also have a much more secure locking system that allows you to securely lock the table in place at many different heights. The cheaper ones use a steel rod inserted through a hole as a lock. They normally will only lock in two positions. If you wish to maintain the lift at any other height, you must rely on the hydraulic cylinder for your safety. The more expensive ones will also lift higher than the cheaper ones. This makes a difference if you are working for several hours at to low of a height and always have to be bent over.
Air operated hydraulic is common now. I recommend this option, it is just easier to operate the lift.
Purchase a centre lift to go with it. Many of the more expensive ones can be purchased with it as an option. They provide a lot more stability and flexibility in performing maintenance.
None of these advantages are insurmountable if the cheaper consumer level table is all that you can manage. I, and many others on this site, use the cheap narrow lift-tables that are commonly sold at consumer outlets. We all do what we need to do with them, and there is no question that they are far superior to working on the floor. However, if you don't mind the extra money and have the space for a wider table, treat yourself. In hind-sight, I would have.
