If money is a real limitation, get a limited slip in your rig. Get it from the factory when you order your rig if you can. But remember, with limited slip, you've got to have tires turning to make the slip limiter work. And when you have tires turning, you've got the gas pedal down. With the gas pedal down, you've increased your chances of breakage significantly. BIG TIME. With Air Lockers, you just let it walk and it's locked. Nothing to break if you're smart about your right foot.
If you're rig is strictly hardcore rock crawling, then the full time, pavement chirping lockers (Detroit, Powertrax, etc.) are an option many guys take. Just don't expect Mom to drive it to the grocery store. Tire chirping when cornering and difficult front end steering is the price you'll pay on pavement. And quite frankly, I've done very well as have others in hard core crawling with ARB's. In fact, I'm seeing more ARB's on competition rock crawling rigs. So it's up to you and how else you use your rig.
If you're thinking about changing gears while you're locking up your rig, then READ THIS FIRST. Please.
