I say go with Auto-Installer Deluxe v2. IT has EVERYTHING you need for modding an Xbox: Exploit packages, up to date BIOSes, dashboards, applications, and documents on how to set up your modded/soon-to-be modded Xbox.
The auto-installer also has a unique way of updating the installer. They've included an updater (PC App) which lets you load the Auto-Installer Deluxe v2 ISO into the app then load the update package next. You click "update" and let it do it's thing. After it's finished, you have an up-to-date installer with added BIOSes, updated apps, emus, dahboards, etc which you need to write to CD/DVD (depending on what DVD-Drive you have)
The only flaw I found in Auto-Installer Deluxe v2 was running the installer on a freshly modded Xbox with a new Hard Drive. When you run it for the first time, you will get an error with a number in the top left, which I forgot what it was. But after updating it, the error is fixed.
Visit the site for anything I missed (Which is a lot of stuff):
http://aideluxe.com/Slayer's is also a good installer for those new to the modding scene. The downside to that is everything the installer installs is too old, including the original M$ Dashboard.
Well, there's my opinion (I'm not too good at posting a review on things)
