From a cost standpoint, my recommendation and the item in your link aren't even in the same ballpark, however you should hear it anyway:
I have one of BLS's lighting kits, and so do many of my TA friends after being able to touch, see and experience them in person. The projector and HID combo, as well as the overall fit and finish of the product in the box were 2nd to none in this category. There isn't a better alternative out there, and 2nd place isn't even close as far as Finish & Customer Support are concerned.

From a performance standpoint: I light up the road as well as, if not better, than my Cadillac does.
As far as your Blinding concern: This was never once an issue with my BLS kit. Just like you, I've been blinded by hack-jobs on the road before too, and that was a large influence on why I needed to have this product on my car.

I'd buy these things again in a heartbeat. While I can't offer any experience with the product in your link, I can only share with you my first hand experience with the Blackbird Lighting Solutiona kit. I would highly recommend anyone thinking about doing their headlights to take a look at their offerings, save up as needed, and keep an eye out for online Group Purchases... they're worth every penny.
