There's a ton of information on this forum, I'd suggest poking around a bit and getting some knowledge. That said, I've been doing a lot of research myself for my wife's JK (on order), and will probably go with the AEV 2.5 lift. It's just under $1k, but I'll add geometry correction brackets, either rancho or AEV, for another $100ish. This kit gets very good reviews everywhere I've seen.
