E55 Xenon Conversion.
1. Buy a cheap HID kit, 6000k for $50.
2. A local custom car shop, (friend who is a installer) said he could get me a kit 100 for the ballast 40 for the bulbs and it comes with a resistor to not throw codes.
3. Was looking on ebay and found these links...

The third option seems like its going to be the most expensive one. I know something similar has been posted on this before but didn't get any definitive answers on whats the best option.
Thanks!
The headlamps were $900 a pair and I sold my halogen headlamps (new condition) for $500 so it cost me $400.
The OEM BiXenon headlamps are now over $1200 and I see OEM halogen headlamps on flea bay for $100-$200.
