I wouldn't waste your money or time on a procomp lift. I used to have a Rubicon Express lift on my old JK (which RE and Procomp are owned by 4wheel Parts, correct me if I'm wrong) and I was far from impressed. I would take your time and save up for a quality setup which it looks like you are going with the EVO Enforcer.
Like mentioned above, a shop will push their own products. I experienced this with 4wheel Parts who was trying to sell me on Procomp as if it was the greatest thing since sliced bread. I was still learning at the time and didn't know the relation between the two lift kits. Lessen learned!!
Best of luck!
