Try topbulb.com. That's where I get my compact fluorescents from. Service could be a little better, but so far, it has been "acceptable" to me.
There are a number of different manufacturers, and at many different prices. On the high end, there are the Ott-Lites, which I've seen for about $35 apiece. I buy the Greenlite "S26" (the brightest I've been able to find thus far...however I haven't searched recently) at $12.50 each (+ s/h). I'm not sure if the S26 is considered a true full spectrum bulb, but the light is very white.
There is also a Spiralux bulb that emits 6700k, which supposedly simulates cool, arctic daylight (whatever that is). I've been meaning to try it, but haven't gotten around to it yet (about $29 each at naturallighting.com).
If ordering from topbulb, be sure to double-check the whiteness of the lights. As you've probably already found out, a lot if not most of the compact fluorescent bulbs out there emit a soft white light similar to an incandescent bulb.
As a suggestion, you might want to try just a couple of bulbs before replacing all the lighting in your home. I put in an S26 in my living room, and somehow that bright white light just didn't cut it. My spouse was not too happy with it either, so it was back to soft white lighting.
The S26 (or S23) is especially great in a closet, for color-matching your clothes. Be aware that compact fluorescents do take some time to reach maximum brightness.
