Greg Smith Equipment has them at decent prices. A lot of my smaller shops bought them. THey are pretty good quality but if you are buying them for a shop buy the next size up because they will get abused and overloaded. Greg Smith Equipment Lifts
They show two (presumably new, as I could find a "used section" unless they are all used) alignment lifts (also called "racks").
One is $8200 and includes turntables.
The listing shows two air jacks bit does not mention them in the text.
Hard to believe they are included as other sites show those jacks for more than $2.5K each.
One is $7300 but there is no text description at all on that one.
Those numbers are a lot more doable for me, and it also says "free shipping" which would likely be a grand for truck freight.
Those are 12K and 14K capacity lifts.
I only really need an 8 or 10K max.
