4000K Narva Artic Blues or Philips Bluevisions are the whitest halogen lights with ADR approval and are around the $70 mark for a pair.
Phillips crystal visions bulbs are 4300K and have more of a 'HID look' to them but they aren't ADR approved, but even still they aren't anywhere near as glarey to oncoming drivers as HIDs. These retail for about $100 though you can pick them up on eBay cheaper.
If you do alot of country driving I wouldn't get HIDs but if you're city driving mainly its upto you, just keep in mind you are risking a defect/fine by having them on...
