Outer Limits 4x4 Board

Need some help on a decision and which way to go!
PROBLEM: Which is a better option to go, I want to
fit a locker to my front diff first and then later to the rear.
Hear in is my problem. I can pick up brand new detroit
lockers really cheap still in box, but have heard that their
a bitch on road . Would this be the way to go or should I
bite the bullet, save up and fit air lockers.
I use the car every day for work and get offroad when ever
I get the chance , any help is appreciated.

buy the cheap one sell it for more and get air lokers

detroit in the front would be very good, in my opinion not quite as good as an airlocker but it wont affect on road handling when its in 2wd and will work very good off road.
