As Gatorayde said, it's best to do it right the first time.
My Jeep was bone stock for over 4 months while I accumulated what I think are the best components from different manufacturers.
I bought the majority of my things new, but some used, always scoring a deal, and lifting my Jeep properly (4.5", no DW even doing 90 on a bumpy highway) on a budget.
People say you can't lift on a budget, I prove them wrong.
JKS trackbar: Get it used, but buy brand new high durometer bushings.
4" Teraflex coils: $160 shipped for all four (Closeout)
4-5" Rough Country shocks: $130 shipped for all four + free boots (JCWhitney). Some say they're too stiff, but I love my ride to be stiff.
Used IRO long arms: $400.
Total, i got away with lifting mine for about $700.
