Well, if you don't count the fact that I bought replacement headlamp assemblies, the Halo kit itself only cost $180 and the HID kit was around $100.

The most time intensive part of the process was actually putting the halos in the headlamp assemblies. It involved drilling the holes in the rings surrounding the projector lens housings in order to run the power wires through for a clean install, epoxying the halo rings in place, drilling a small hole on the back side of the assemblies to pass the connector wires from the power inverters through, connecting the power wires to the inverter wires, then reassembling the assemblies and sealing the lenses back on.

Not counting the time it took for the silicone sealant to dry, just putting the halos in the assemblies took about 3 hours. It would be much quicker if I was to ever do it again, because most of the time was spent figuring out the best way to actually go about setting it all up. The directions provided by oracle aren't exactly specific to the Crossfire. once the assemblies were ready to be installed in the car, that was only about an hour process as all you have to do is wire the inverters to power/ground once the assemblies are in. HID's went in at the same time and were extremely quick, as well.
