I used to think the same thing as you, until I start looking into the subject. It's only some of the sellers that carry colors that low. Most usually focus from 5000k and up.
Originally, I was going to order them from HID4U on ebay. People who've gotten HIDs from him on F150online seem to like the results. The only problem I've seen is some people's ballasts going out. The general theory on the cause is because they aren't using relays connected to the battery.
Then, someone posted a link to another seller, retro-solutions, on ebay. Seems they have a lifetime warranty, which is a plus. Also, they have the 4300k color for the 9006 bulb, which is also nice.

They have the 3000k for you, EGTFitz.

Here's their website for the F150online pricing:
Click Me. For the 9006 kit, their ebay store is 5 dollars cheaper than the group buy price.
