slim line ? you mean low pro right.
Well I just picked this up from harborfreight today.
- Harbor Freight Tools - Quality Tools at the Lowest Prices Very nice!
As you can see on the website 2 3/4 min height, 75lbs. Also just used it today the release is very smooth, easy to let down slow, easy to control, solid ass jack. I actually was in time for the 15 percent off got it for around 83.
You dont need aluminum if you just gonna use it in the garage.
