Lockers are next on my list of big things to do; I'm only looking to put in a rear locker. The lunchbox-style really appeals to me, because it's cheap, easy to install, and simple. I've seen individual threads about all 3 of these on here, but never a thread comparing them. I know they all work and do basically the same thing, but would anyone with experience with them care to chime in and talk about some of the differences between them? I am leaning towards the Spartan right now as it's supposed to be beefier, but apparently can be noisy.
