Best gears and cheapest place??

[jsbihn]

I am looking to purchase rear gears for the rig.

I would like to find something that would improve my get up and go, but not make it so get up and go that i loose the ability to move through the off-road and mud if i want.

I have heard of many gear setup
So i am trying to find out who all has gears and what they have and what they think of them

Also, I would like to know the cheapest place to get the gears.
Usually the gears arent that much, it is the install that kills ya
And it bothers me when something that is usually a cheap item on every other car (or is the same PN on another vehicle) is charged up in price just because of the vehicle (ie. like a exhaust for my Vette costs 500 bucks, but for my M3 it cost 1500 - OR - a camshaft for the Vette costs 500 but for the Hummer it is 250 bucks ** just examples mind you **)
