I bought a used gas station lift for $500 and it has worked great for all kinds of servicing, brake and shock work.
I made an adapter for my bike but didnt like it so have a new plan there. I use it to service atv's, sleds, garden tractors. Works awesome for removing the blades and servicing the 3 pt mower.
I find I do a more thorough job and find many things I am sure would go unnoticed working on the floor. My knee's give me issues and although I have one of the "Dog Bone" deluxe creepers it is very dusty. I use the large pallets from a hot tub shop on it for ripping down sleds or even as a welding table at times.
Also works good for loading bikes and sleds or anything heavy in the shop. Get it on the lift and raise to height and back up to it.
