Wade,
I hope to have mine up next week. It is a Danmar Brigadier 10ACX, 10,000 lb. 220 volt two post lift. I ordered it from Best Buy Automotive Equipment,

I did lots of research on lifts some are cheaper some more expensive. I watched the videos of them testing lifts and them failing. I watched videos of lifts in dealerships failing. They call for a 4 1/4" thick floor 3000 psi concrete with reinforced steel bar for foundation. Since I had not poured I dug deeper under where the columns go and made 8" with 1/2" re-bar frame set in the concrete. This lift is tested and certified and many of the cheaper ones are not. It also had free shipping and an extended 3 year warranty, $2,440.00. Some only have 90 day. During shipping the trucking company scratched the paint and damaged the decals. When I sent pictures they sent me touch up paint and new decals with no questions asked. The install is drilling some 3/4" holes in the concrete and setting the uprights. It weighs a little over 1,600 lbs. and I came to Greenville, S.C. to pick up at truck terminal. My builder is going to help me set it up.
I did run my electrical under my slab before pouring but you can run overhead also.
Take a look at their web site they carry pretty much any equipment you might need for a shop and 2 post lifts go as low as $1,340 for a 7,000 lb. lift.
They do make lifts for low ceilings and also portable. I like a two post lift better than a 4 post you can get to everything easier. A 4 post lift just lifts the car up so you can then jack it up and you have all the lift in your way. This two post lift has nothing on the floor just the footprint of the column. I did talk to local shops and found none that preferred a 4 post over a 2 post.
You are welcome to drive up the mountain and come see next week if you want here in Hendersonville, N.C.. I doubt the power will be on I am in the process of wiring the garage now and one man 68 goes slow, lol. My shop has 14' eve height. Not sure what the minimum is but should be one the web site. They also had carts for Mustangs made by Auto Twirler but the shipping was about as much as the cart so I cancelled that order. Got a hose reel and wheeled tall oil change bucket also.
Rain delays and builder for the erection over booked have set me back about a month.
You can PM me and I will give phone and address.
Install is like most things not rocket science you do have to drill 3/4" holes in the concrete and will need help to stand up the columns. The electric I think is 220 single phase, 20 amp or maybe 15 amp but just three wires either way.
