I just regeared my 98' with 4.56 gears for about $1100 at 4 wheel parts. I had 3.07 gears and it made a big difference. I have a 5 sp manual as well and I gained a whole gear (I can start in 2nd very easy) I also have a RE 3.5 lift which is about 4". The only sacrifice is hitting 3000 rpm in 5th on the freeway at about 65mph. (but at least I use 5th gear now) I have 33" BFG KM2 tires. Overall it is great and I am very happy I went with 4.56, I think 4.88 would have been too low for me.
