Very nice, Neil. Thanks for the 'horizontal, not vertical' tip.
I somewhat agree that there comes a point where a mod isn't financially viable if you over-analyze it. But I think you could recoup 156 bucks. Maybe not on its own, but in concert with all the other mods you got going on...
For me, it's somewhat of a hobby. Kinda like the guy who goes deer hunting and proclaims, "This way I don't have to buy beef!"
