I was plesantly surprised with the build quality given I picked these up on Amazon for $189 (w/ free shipping). The kit also included brighter regular & high beam Halo bulbs. Now that I have projectors I plan to upgrade to a Xenon 6000K H4 kit soon.
*EDIT* The Spyder kit uses H1 in the projectors, not H4 like the OEM headlamps. This also explains why they ship w/ Halo bulbs included.
