We had a comment about where to get dimmable CFLS by mail-order. Try these vendors. Between the three, they offer the most variety and pricing for the dimmable flourescents. And their selection of regular CFLs aren’t bad either. If only we could get the local home improvement warehouse to carry them.

Where to Get Dimmable CFLs
I used a non-dimmable CFL with a dimmer switch once. Bad idea. The thing blew out in about a month and had a huge scorch mark. I’m lucky there was no more damage.
