DDM tuning has lowered their prices to $25 for the single bulb system! That's with the slim-all digital ballast, and everything you need to install it. There has been a lot of discussion on the merit of HIDs in the past on this forum. FWIW DDM claims a 6 amp draw on start up and 3.4amp during operation. All I can say is that I love my HIDs and I wouldn't go back to normal bulbs! I just ordered a kit for my girl's bike!
