I have to agree with Pat/Ohio I have had a Backyard Buddy lift for many years with no problems. Perhaps the safest 4-post lift on the market. They are a bit pricey. I believe I paid around $3,200 fifteen years ago. Purchased the taller one to give me more head room. They are made in Ohio with USA or Canadian steel...no Chinese stuff!

I have looked at them all and am staying away from the Chineese / off shore ones. Looking at the steel that the off shore / Chineese use is a bit thinner and are made of sheet stock bent then welded not like the ones made in the US that use extruded thicker material. I am looking at buying at least 4ea lifts and would not even consider anything but US made. Keep my money here in America.
