And within the "locking units" category, you have three types.
Lowest end of the scale and easiest to install is the "lunchbox locker." This is a basic unit that uses the factory carrier, but replaces the spider gears & cross shafts. Very popular in front differential applications in 4wd.
Next is the full locker, which completely replaces the factory gear carrier. Stronger than the lunchbox style, it also (generally speaking) has manners that take more getting used to. Some of the clunking, clicking, etc. that Patrick mentions.
Last is the manually-selectable locker. These are operated either by onboard compressed air (ARB locker) or a cable linkage (OX locker). When unlocked, you have a completely open differential. Throw the switch or move the lever, and you essentially have a solid spool. Another, fairly new, variation on this is the selectable locker offered in some Jeeps, like the Rubicon. It is electrically actuated, acting like a limited slip when disengaged, and becoming a solid spool when engaged.
The Power-Lock is noted amongst Jeepers as being about the best limited-slip ever offered from the factory.

I just wanted to let you guys know that you have all been so helpful with this thread. I made my decisions awhile back and I now am the proud owner of a deluxe pallet kit with a 3:54 posi in which I will be attaching my 427 Ponds SO to a Tremec TKO600 5 speed. Not very traditional I know, (I'm sure Alan could attest to my lack of convention), but definitely will fit to my driving situation. You guys have been really helpful and I am thoroughly impressed to see this thread still being viewed and discussed. I also wanted to thank Alan for helping me through those tough decisions. I am finishing up my body buck right now and anxious to move on to the next step. I know my children will be disappointed to see the body come off, because they love getting in and "driving". Thanks for all of the input.
