Rough Country makes very good lifts that wont cost a fortune, you can get a 2" budget boost lift for $110 or the 2.5" progressive spring lift that will ride very nicely on the street as well for $300. They also have reasonable height body lifts that are inexpensive too, 1.25" body lift, easy to install $100, also with a body lift you can do a motor mount lift to keep the transmission and transfer case linkages where they should be for $100 as well, all easy to install with basic tools and good floor jack.
