The good thing about the G3 and G1 is that you can just "drop them in" without cutting so it should be a quicker installation. That would allow me to buy a second set later if I didn't feel like pulling them apart again to go back to OE prior to bringing my X in for service.
Also, can go back to OE without any problem... other than having to re-heat to pull the lenses off, but still doable.
Oh well, guess I really need to think about this. I think I can get some FX-R projectors for $175-200 on eBay. Plus another $100-150 for OE housings to have as spares. Plus the cost of the HIDs I already bought (guess I don't need to count those since I already bought them, but I will for sake of total cost). Total is about $365 - $440 not including personal time.
I still want to do it, but will need to save up some cash to probably go all in on this project.
