I dont know what its like for MB but there is a large conversation about Phoenix Microlight HID conversion at:
http://204.198.130.69/forum/forum_6/wwwall.htm
I have to warn you, this page is HUGE, and its takes a long time to load.
But from what I heard, everybody is getting the conversion - I would reccomend euro headlamps and HID conversion
