One of the reasons I've stayed away from CFLs is because I like dimmers and have one everywhere excepts closets and the kitchen. But I did find a web site that has a good selection of instant on and dimmable CFLs at
1000 Bulbs
The former owners had standard CFLs everywhere, and I took them all out and gave them to my "green" boss. I still can't figure the lesser of two evils between energy use of incandescents and disposal of CFLs.
