Philips - got one on my BMW K1200LTC - incredible. http://www.hid-online.com got it within the week. Easy installation. I only had to bend the retaining spring - no trimming of the bulb mount so that if you sell your bike, you can sell it with the stock stuff and keep the HID for your next bike.

e-mail/pm me and I'll give you the contact information for a real expert on HID at Phillips.
