There are a couple of threads about the quick jacks, people seem to like em. I've been debating the 7k weight limit one so I can lift my DD F150 as well. Costco has pretty good pricing on em, I wanna say $1,200 shipped for the 7k unit
I doubt you're going to find anyone much cheaper. It's a long process. It's why a lot of people stick with stock manifolds.
