I've seen some bulbs that are as low as $45 (price+shipping) for a pair of replacement HID bulbs. They are either from unknown origin or asia. The feedback is usually good, but I know it can be useless since it's only a feedback after a couple of days the customer receives the item. Some, however, are second or third time buyers and they left good comments. On certain items, they give 1 to 1 1/2 year warranty. Do you think they are worth buying? Thank you for your helpful answers!
