If you're lucky, you can find some barely-used stock JK rubicon shocks for cheap. You do have to take some of the hardware off of your stock shocks to make the JK ones bolt in, but for like a $60 set of shocks with only 200 miles on them, they'll ride better, for longer, than super cheap new RC shocks. That, and they're good for anywhere from about 3" to 5" of lift.
