Check that the CFL has a broad dimming range. Some will ramp up very quickly to almost full brightness leaving a very sensitive or narrow dimming range with flicker. You already know that CFL will not dim down to a glow like incandescent. Most importantly, some CFL will make a lot of power line noise that will interfere with your X10 or Insteon. In my home, I've had to install a double gang box and have a Leviton X10 filter in the OUTPUT towards the bulb to prevent noise from desensing the switch when the lamp isn't full on, or full off. In this case, I'm using a dimmable GE R40 lamp.
Some other poster in this group a few months ago mentioned a brand of CF lamps that are labelled non-dimmable, but dim quite nicely, thank you. I can't remember the brand, but perhaps a google search will uncover this. This would save you a lot of money.
YMMV, but I'm thinking that dimmable CF lamps have a narrow application. For mood lighting, you just can't get that dim glow. For the front of my house (outdoor lighting), I'm using a Switchlinc Relay with CF lamps. Works great. The savings in energy are such that I'm not worried about CF power consumption in comparison to incandescent.
