I'm interested in putting together a super cheap indoor lighting setup to try my hand at doing headshots. There is a person in my area selling a very inexpensive backdrop and 2 light setup with stands and umbrellas. The lights and stand heads take those curly lightbulbs.
The problem with the lights you linked to are many. First, each one only has a single bulb so there's not a lot of light to work with.
Second, what light there is can't be controlled in intensity other than by changing the light-to-subject distance, which changes not just the exposure but also the quality of the light.
Third, the fixtures the bulbs are mounted on aren't right for that kind of bulb; with no reflectors, very little of the light is being directed into the umbrellas; most of it is being spilled out in all directions.
I know you want to go cheap, but this would be a waste of money in my opinion.
Continuous fluorescent lights do have a place in the studio, but cost isn't the main reason for getting them. If you want to go with CFLs, the minimum setup I would suggest -- other than building something yourself -- would be this one:
While you're saving to get good lights, you can do like renowned headshot photographer Peter Hurley did when he first started: stand with your back to a large north-facing window, and use natural light exclusively.
