well its only labour. im using holden vy series lights and basically cutting the surround down to size. then u melt your healidht, unscrew the existing surround and fit this one in with a few cuts.
you could do it with any projector lense headlight, but it depends how neat u want it.
im getting the parts for free from a crash repair, and it looks like a 100grand merc when its at a set of lights.
replacement cost of the holden headlights is 360 each to buy so depends how much u want it, otherwise u have to wait for a crash repairer to get some. im still waiting for the left side to finish.
but u do need H11 globes @ 45 each otherwise a H11 HID kit at around 350-400
