If you haven't already, talk to the forum admin/owner Rick before getting too serious about vending round here, just an FYI if you weren't already aware**
As far as HID's go, I've got two sets from DDMTuning, 35w digital ballasts with 9007 and 880 series 4300k bulbs. LOVE THEM. However, the digital ballasts have been my weak point. I've had two go bad and have a third one that seems like it's on its way out ((they've replaced the last two)).
Would be very interested in checking out the quality of your stuff if you can match DDM's prices and customer service!
