Lumiko makes some good long lasting ones for $60/pair on the street. You can also try the new Sylvanias for $50/pair. PIAA used to make some flaky ones, but their new ones seem a lot better but at $90/pair is a little pricey. I'm using the Eurospec Phillips Vision Plus but they're not white ... normal OEM look but close to HID brightness and range for $30.
man never get nokya. they suck ass plus they have really really high wattage which can damage somethings since it gets so hot. also is hard to see at night. i use to have them (because it was cool to have really bright headlights) and when i was taking a corner i couldnt see the center divide a lot of the times. so i wouldnt recomend it.
sylvania silverstars are very good. they are 50 bucks a pair though. you can get them at kragen and they have rather low wattage.
