I am going with the FlashLogic
FLRSCH10 from eBay that
@Hemi395 recommended - Basically Plug and Play, does require programming but no mailing the unit back, you program it yourself on the Flashlogic website with the included flashlogic cable. It's legit programming unlike Doug's "shared dealer login" deal that got his account pulled, and less that $150. Got mine here.

I would like to have gone with the Mopar unit, but it's $260 for the kit and then either a 3 hour labor charge for install, or an $135 charge for the flash if I installed it myself. So about 3-4x as much. IF I lived up north I might have considered it more, but since I am in Florida I won't use it as near as much as someone up in the cold weather states, and went with the lesser cost aftermarket solution.
