We are already 15 pages in here. Might as well come to some sort of a conclusion as you've strung us all long this far.

A good way to look at it is a value comparison. So, what do you offer the X5D customer? In terms of cost and performance increase? Maybe we can find an independent party to test both and while considering price and ease of install/removal have them highlight each and what they feel what offers the best value and overall experience.
