new or used? Built or bought?
Depends how picky you are about it.
You can buy one complete used every once in a while here if you can wait for it don't know how a good a deal it is though.
Lets say you want to build one since the shipping kills nearly every deal for people in AZ.
YOu could go with the iron pumpkin OEM trac loc from a SC and add the cheapest gears you can find for a little less than 200 So thats most likey 80 bucks form the jyard for the pumpkin. Get a rebuild kit and do the build yourself or take it to good shop aka AZ differential where it would cost about 400 bucks to have it all rebuilt and them supplying your new gears and rebuild kit and maybe even putting it in your car. And you can use cheaper oil or expensive oil post break in period. The cheap goes for less than half the price.
I went a much different route. I bought a mark8 case from the junkyard, trac loc by itself from tccoa, billet flowcover brace from scp.com, used 2.25 qts motor craft full synthetic gear oil from the dealer+frict mod, a rebuild kit and 3.73s from scp.com as well. The trac loc was rebuilt for more heavy duty use before it arrived to me 4 clutch stacks and f150 s spring. The parts where all dropped off to a shop. I went to the most reputable shop in my area AZ Differential and later on I put complete unit in my car myself. These things don't come together quick for everyone because you either hunt donw your trac lok or by a new expensive one. That alone changes the price wildly. A cheap price to build one would cost $550+ to do it. I spent much more than that like $850+ but mine can handle more punishment with the right oil and brace. I know is done right and never needs touching. I spent more than I want to admit but if you research what I bought you get the idea of how much it will cost you to do this particular set up. The gear oil I bought was 18 bucks a quart plus 2 bottles of 10 buck friction modifier to boot. I broke the unit in with cheap supertec gear oil first though.
