Front camber adjustables, anyone??

Ill be lowering the car come spring, and im not goin to do it without a front camber adjustment. I can do the rear for free (duh) but I have a few choices for the front. They are mostly totally different approaches to camber adjustment. Anyone have any experience with any of these, and can say yay or nay to any brands/styles?? Wanting some feed back before forking out a couple hundred more dollars.

Thanks in advance.

Nothing? Thats ok.. ill pick one and do it. Ill be sure to let everyone know how they seem to hold up, and how well they hold the adjustment.
