I like asking dumb questions, so I apologize in advance...
Why do you want to do the lift?
If you want to do it mainly for appearance, which is not a bad thing at all since Jeeps with huge tires are awesome, then the prices greatly depend on exactly how you want it to look. The appearance is mostly a choice of which tires/rims/shocks you use. You can put 35s on the factory 17" rims at a low-low price of $0/each per rim, or on $1000/each rims, or anywhere in between.
If you are doing it mainly for offroad performance, then I suggest taking your Jeep out to easy trails a few times first to see what you really need. Depending on where and when you go you might find that your money is better spent elsewhere to start.
The 32" tires on my Rubi offer me "plenty" of clearance for the nearby easier locations, and I have to drive a long way to get to any really hard wheeling locations. I do, however, frequently find myself out after dark.
I've decided and purchased a very nice set of offroad lights first, since I wouldn't gain that much from bigger tires quite yet.
