I drooled over lifts for my shop for ages. I had a deposit on a Revolution lift, but my garage does not have the clearance. I have spent many hours contemplating lowering the floor and now it is raising the roof. Since I do not like building inspectors or tax assessors I have held off going through with it. The one I fancy at the moment is the Bend Pak 9000 pound one. I'd make sure you get one from a reputable company. Don't buy a cheap lift that doesn't meet lift association specs. They are pretty well all made in China now. The Good and the not so Good. The other thing you might want to plan for is an air Compressor. If you want to bead blast or use a decent amount of air for painting, etc. , 5HP is the minimum. Make sure it has a cast iron cylinder. Plan on having excellent exhaust fans if you want to play with anything that makes the air bad to breathe. Lighting is key to a shop. I went with a whole bunch of daylight flourescent overhead tubes. Lighting is very even. if you plan on heating with electricity or might do some welding get a 200 amp panel in the garage . Insulation where I live is very important. I had the shop spray foamed before finishing the drywall. My garage doors are also filled with foam. A large steel covered work bench is great to have. I recently completed this and it was a great moment in shop enjoyment.
Friends often ask me what I build in the shop....mostly the shop is what I build. I should put a plant around the E9, as it might as well be in a living room.
Other things that make it more capable and comfortable. Small fridge, Oven, Drill Press, eye wash station, stereo, security camera, alarm, first aid kit, emergency backup lighting and a life long collection of mostly used tools. Heat, AC. incinerating toilet, Water tank, small office, old MAc Lampshade computer, lot's of fire extinguishers. It is easy to get carried away with the garage. My house has been neglected for a few years now.
