There is a tremendous amount of variation in quality of light from compact fluorescence. Don't buy the cheap ones, you won't like them. it's been my experience that if the package doesn't have a color temperature rating, then the light will be green, sometimes worse than the ever present pea grean luxeon!
I bought some Lights of America branded CF's years ago. The first batch of their tall ones (non curled) were terrific. I'm still using several of them 4 years later. The second batch I bought all had the ballasts smoke (quite literally in fact) within weeks. I don't know if they have cleaned up their quality control since then, but I won't be buying from them again.
Lows seems to only carry sylvania branded cf's here. I bought once of the tiny spiral 75 watt ones. This light probably has the best color temperature of all of my CF's. It's a very good white color and it's small enough to fit in almost any fixture. Cost is good too, around $5 if I remember correctly. The only downside is that it takes a heartbeat from when you flip the switch to when it lights up.
Home Depot is selling a lot of lights from, I think it's "community electric" or something like that. I bought 3 of their tiny twist lamps for the kitchen fixture because they were rated for enclosed fixtures (which many of them are not and they will burn out in a hurry if you seal them in!) These are not quite as nice a light as the sylvania. They are instant on, but take a few minutes to reach full power. When starting they are very greenish, but the color improves as they warm up. I also have one of these branded lights that tries to look like a regular bulb, with the CF curled up inside it. As far as I'm concerned this light is useless. It's DIM, very green and takes a long time to warm up to any useful brightness.
Home depot also sells phillips marathon bulbs. I own 2 of the 3 way 75/100/150 bulbs, and they are VERY nice. Also VERY expensive. The light color is very good, but they also take a moment to light up when you turn them on.
I have lots more info on reflector type lamps and other use with X10 modules and whatever if anyone is interested;)
