Most folks are satisfied with a PnP kit using stock halogen projectors. Sometimes you get lucky and the HID klamps work pretty decently with a halogen projector. The difference between the projectors is purely the optics which involve the reflector bowl and position of the lamp. Halogen lamps have a different focal point than HIDs. HIDs have a tighter and more intense light source versus halogen. The rest of the projector design is simply based on how it can reflect the light out of the projector.

With all that said, I'd see if others have posted output shots using the halogen projectors and HIDs. The TRS kit is $150 for lamps, ballasts, and harness. Projectors run another $130 or so. You can try the PnP kit and worst case, do a retrofit down the line if you aren't happy and are only out the cost of new lamps.

Retrofitting one projector for another depends on how easy it is to remove the existing unit and if you can figure out a way to cleanly mount the new one. Rotation is where most screw it up.
