Looking for 2 post lift recommendations

[ixlr8]

Hi folks, I am looking for 2 post lift recommendations, and education. I know NOTHING about 2 post lifts, I see talk of symmetric, asymmetric, supersymmetric, 2 piece, 3 piece and solid arms, I have no idea which is which and what advantages each offer. I will be lifting everything from a golf cart, a sidebyside to my 3/4 ton truck. The slab is 5" thick of 3000psi concrete. It might get used 8 times a year so I don't need anything super heavy duty, but I don't want junk. I'm 6'2' and I want to walk underneath it without banging my head. I have 15' of clearance from the floor to my high lift door. Floor is slightly tapered due to local code requirements so water will drain out the door. I am guessing I will need to shim the posts so they are perfectly vertical. Would prefer it to be a certified lift. Any guidance, or links, that would help me will be appreciated. Thank you

I found a nice used (at a dealership) Rotary brand 10k 2 post lift. For $1000! A fantastic deal.
It had the original selling companies stickers on it with some annual inspection stickers.
I have radiant heat in my floors and between this and no paperwork or familiarity with this lift I called them about installation. They quoted me $400 and I didn't hesitate for a second!
Although I didn't buy my lift from them, they might be worth a call about finding either a new or used lift. They're in the Portland ME area and seem to be a source for general commercial shops with the lifts and oil distribution, probably parts cleaners etc.
From my little dealing with them I can't say enough good things.
They had the few necessary miscellaneous on their truck and did some lubricating along with the assembly and installation for the $400 that they quoted. 2 man crew.
Ever since I got this phone I haven't been able to load pictures here. Other sites are fine. (I took a picture of they're stickers and info for you.)
They're name is AGT (automotive garage tools) and their # is 207 878 8811
Just internet your lift questions to help your shopping knowledge.
