Unless you are a pro mechanic or a racer, I don't really think that you need to buy expensive motorcycle lifts especially if you are only doing small repairs or Sunday maintenance on your bikes. I had several hundreds of bikes but I never bought a proper bike lift. I do have a portable bike lift for off-road bikes but it can't be used on road bikes. I sometime use car jacks to lift bikes but I personally prefer hanging bikes on a chain block, makes lifting easier and safer. You can always get car jacks cheap or for free at scrap yards near you. Just work slowly and best if you have somebody to hold your bike for you while you do your repairs.
I don't have anybody to hold bikes for me so I use bike tie-downs. Bike tie-downs are very handy and can be used in many ways. Try to keep at least two bike tie-downs in your garage because you never know when you will be needing one.
