call around to your local 4x4 shops that do lifts, many have used factory springs laying around for the "cheep". Make sure to state non LJ springs, you get a 1/2 to an inch extra lift from them. Your local club boards are another source.
I have a set of XJ coils, stock out of a 99 and were removed almost 10 years ago. They have been sitting in my shed for 10 years. all yours, just pay for shipping from Massachuseets. But might be cheaper to just pull them from a yard local to you though.
