I'm in the process of planning a shop that I will hopefully get built this fall. I'd like to have a lift. The ones I'm thinking about mount above the floor (no cylinder down in the floor or anything) and I think some have two posts while others have four. I have heard that there are some foreign brands that should be avoided. Anyone have one of these? Anyone know of some good brands to look into. Obviously if I'm gonna walk under a 5K lb. truck I want the lift to hold it .
