Where can I get a good ballast for 08 g35
 

My ballast went on my g35 and I bought one off amazon and i give up from the place I got. ONe worked a few weeks, they sent me another and that worked about 6-8 weeks and it still does work but goes out a short time after, then sent another and that one just made a buzzing sound and light was very dim.

They were very nice and kept sending me new ones no problem but i told them I give up. I tried 3 times. I am still using the second one they sent me because it kinda works sometimes.

Anyone know where I can get one thats not gonna keep blowing out every month or two? I do not want to go and buy the whole assembly because nissan wants to be greedy and wont make the ballast itself.
