lfhoward said it pretty well. There is no quality lift for around $500(unless you find one used). It will all be spacers or springs that are rated the same as stock which means they will sag quick.
If you chose to save up more, you can pick up Old Man Emu (OME) 927 front springs and 731 rear springs for 2.5" of lift. Then your choice of shocks. Bilstein will probably be the cheapest while still being good quality. You can add to it for 3" or 3.5" if you want to get aftermarket upper a-arms.
BUT, if you need to lift and don't want to save and chose to go spacer, Daystar will probably be the best. Or I've heard Rock Krawler(if you can find a used kit). RK is a 3.5" kit with a longer clevis in the front and spacers in the rear.
If you chose Rock Krawler, make sure you buy grade 8 hardware. There have been more than a few shipped with lower quality hardware that isn't safe.
Another alternative is you can buy 1/4" spacer plate, and do a 3/8" clevis lift in the front, then stack 2 extra upper rear spring isolators per side in the rear. The front will then come up about 1.5" and the rear will be up 1" from where you currently sit. That can all be done for less than $100. On a side note, if I remember correctly (normally do

) new-stock height is 18" front and 19" rear both give or take a tad for factory spec allowances, so you can either have the rake (with 2 extra rear isos), or put 1 extra rear iso per side to sit level.
