i got mine from:
http://stores.ebay.com/wholesale-hid
i paid $50 in nov/dec '08 timeframe. they work great so far and no bulb out indicator. i bought the 4300K H7 for low beam. i have noticed that if you turn them off and back on quickly, sometimes 1 or both don't light - and the bulb out indicator is on. i hear this is normal with HIDs and 1 reason not to put them on high or fogs.
